Yes. However, the concept of BothAnd didn't come from ancient philosophy, but from my research on ubiquitous Information. Like some pioneering scientists, I concluded that the fundamental substance of Reality is not Dualistic (energy + matter, or mind + matter), but Monistic (it's all Information in various forms : mind + energy + matter + everything else). So, the essence of BothAnd is Monism. The "BothAnd" label is simply an indicator that truth is not polarized, but a continuum.
However, as I've always been concerned about, doesn't your Both/And Principle violate 2 laws of logic viz. the law of the excluded middle and the law of noncontradiction (given a proposition p, either p is true or ~p is true but not the case that both p and ~p are true/false at the same time). As an illustration, either theism is true or atheism is true, but both can't be true and both can't be false. There can be no middle ground betwixt theism and atheism. — Agent Smith
The "excluded middle" and "non-contradiction" rules are presuming that you have access to absolute all-encompassing Truth. But the BothAnd rule assumes that we humans are all limited to small bits & pieces of perfect Platonic Truth. That's why I compare it to Einstein's Relativity : the truth you see depends on your "frame of reference", your limited perspective. So, for us earth-bound truth-seekers, it's all "middle ground".
The point is we can't discuss metaphysics for it's impossible to justify any claims we make therein (pure speculation is all that we can manage). . . .
By the way, Nagarjuna's tetralemma is known as the middle way because it rejects/negates extremes. — Agent Smith
Since I consider Meta-Physics to be the sole purview of Philosophy, I wouldn't agree that we shouldn't discuss non-physical (e.g. mental) topics. What else are we going to talk about, the weather? Even so, we cannot make any absolute claims about non-verifiable or non-falsifiable bits of truth. Philosophy can only allow us to get "Closer to Truth". As the link below notes, despite our best efforts to "know the mind of god", philosophers, by "exploring the deepest questions" can only hope to improve their own personal understanding. Beware of prophets who claim to reveal the absolute Truth. However, the Enformationism thesis is intended to suggest a way to approximate a Theory of Everything.
The rejection of extremes is definitely akin to the BothAnd view. However, it's statistically possible that the balance point of Harmony could be at one extreme. For, example, a rule against torturing babies may be as far as possible away from Sadism. But such clear (radical) oppositions are rare.

What's the Point of Philosophy? :
“It is suggested that the intrinsic point of doing philosophy is to establish a rational consensus about what the answers to its main questions are. But it seems that this cannot be accomplished because philosophical arguments are bound to be inconclusive,”

The Mind of God is a 1992 non-fiction book by physicist Paul Davies. Subtitled The Scientific Basis for a Rational World, it is a whirlwind tour and explanation of theories, both physical and metaphysical, regarding ultimate causes. Its title comes from a quotation from Stephen Hawking: "If we do discover a theory of everything...it would be the ultimate triumph of human reason—for then we would truly know the mind of God."
The Enformationism thesis is a sort of Theory of Everything (TOE), in the sense that "X" is supposed to be the cosmic All, of which our world is a small part. But it is not a scientific model of reality, and it does not claim to be the absolute Truth. Instead, it is merely a framework for my personal under-standing of the enigmatic world I found myself wandering in, like a stranger in a strange land, as an unfledged babe. It's also a response to the babble of rival theories-of-ultimate-reality -- religious & scientific -- that only added to the mystery.

Note -- "X" can be imagined as G*D, Logos, Programmer, Creator, The All, The One, etc. Sadly, as the part cannot know the whole, we may never know the mind of "X" for sure. But we can guess.
