I used to think like you, and even had such a function in my .emacs (to
cope with 20.7, 21.[123], 21.2.9[0-5], EMACS_21_1_RC and HEAD).
Now I don't. You say:

but the right test is:
- I want to use feature/fix A
- therefore, I test whether A is available.
Whether the feature is available in version X.Y is not that clear-cut,
specially if you're testing for a feature that appears in a branch
before being installed in the trunk (or even as a temporary measure,
while another, better fix is installed on the trunk). Checking for a
particular release is pointless, because you're not really interested in
the release, you're interested in the feature.
What's wrong with using fboundp, boundp, facep? There are 23/11/6 of
them (respectively) in my .emacs and it works really fine...
