Having the macros is OK, but we should discourage lazy-riding on them,
as it tends to assume an API/ABI stability, that doesn't exist (at
least not on Fedora in that extend).

For example F7 has foo-1 and therefore the packager of bar thinks it
would be easier to query the fc7 or f7 macro than to check for foo's
version. On the next update of foo to foo-2 package bar and it's
specfile break.

E.g. add something like: "Try to avoid explict conditionals on the
distribution and prefer testing for features instead"
