If you mean "EAPIs don't have to include every feature that was
included in a previous EAPI, and can do things differently from
previous EAPIs" then sure. See, for example, dohard and dosed being
removed in EAPI 3.

If you mean that "EAPIs can change the meaning of older EAPIs", then
you're wildly misunderstanding how the whole thing works. We couldn't
use EAPI 3 to say that "it's illegal for EAPI 0, 1 and 2 things to use
dohard and dosed"; that would defeat half of the point of having EAPIs.
