But transistors can be N or P-channel, so it’s not a single logical primitive, like e.g. NAND-gates.

True.
NAND also use both N and P-channel transistors, and have to use at least the same number, but frequently many more transistors for anything non-trivial.
But as you point out, as a computational basis, pass transistors have two variants.
