I think it doesn't make sense to have a policy allowing the sharing of
installed Python scripts across versions. If this were a policy then it
would mean that the scripts could never use new features of gdb's Python
layer -- but that's clearly an absurd result.

For the particular patch in question, it seems to me it would at least
need a comment to be accepted. Otherwise the point of the additional
test is obscure.
