KK, you left out a couple of important "details."
(1) The number of times the position has occurred in recent master & GM games is
one of the defining properties. You forgot to mention that one. Noone would
care about a position which occurred rarely in modern practice.
(2) Similarly, noone would care about a position which did not serve as a
critical juncture point in current chess theory.
Tabiya positions occur often in current GM practice and are critical juncture
points in current chess theory. These properties are practically the defining
properties of tabiyas. Note that unimportant positions would not recur often in
GM play.
{P.S. Sometimes, however, a position is popular, and hence occurs often, for
years and then someone finds a new idea and the position quits occurring. After
some date, you just don't see it anymore. Current theory is the only thing that
we should be concerned about here. This is one of the pitfalls of blindly using
a large collection of GM games to define an opening book.}
