Yes, it has my general support. The proposed terminology is good.

Possibly the following are just more detailed expansions of the existing
* Forwards compatibility. Users would like their programs written
against the 'core' packages to continue to work, without
modification to source text or build system, after upgrading the
compiler, or its packages, or switching to a different compiler.
* Backwards compatibility. Users would like to be able to take a
program written against some version of the 'core' packages, and
build it with an older compiler, accepting that they may have to
install newer versions of the 'core' packages in order to do so.
It may not be possible to fully achieve these goals (in particular the
latter), but that does not mean we should not aim for them.
