Indeed it is ofter better, but why are you saying that to me?
I did not propose to replace a version test with a feature test,
or vice versa.

I proposed to handle existing version tests more efficiently without
any change in the source code.  Others had proposed (or so it
appeared) to change the syntax of some version tests, to optimize
them, and I suggested we could optimize them better without changing
their syntax at all.

If people propose to change some version tests to feature tests, I'm
not necessarily against that.  It might be a good idea.  But that
seems to be a different question.

If we consider that, we need to look for the best way to handle these
new feature tests.
