There's no need to set up a strawman.  I expect that everyone
installing a version of a package is building from the same sources.
Do you really not see a problem here?

Okay, taking a different approach, what does an auto-incrementing
suffix gain us?  The ability to auto-merge a live ebuild at regular
intervals?  That's something that can easily be achieved without
mucking about mangling CPVs, in any implementation we decide on.  What
is it about your particular idea that makes it worth the numerous
disadvantages that we've pointed out?

This is the first time you've mentioned this.  Where would you find
such information?  How would you know that the ebuild the user is using
is a generated ebuild, and not just a standard ebuild that happens to
end in _pre6?  How would that information get into the ebuild?  Would
it have to come from the various VCS eclasses?  What about those that
don't have a way of getting at the revision number (like say
cvs.eclass)?  Would it have to be placed there by the package manager?
If so, then we're back to having to implement support for every VCS
inside the PM.

Could you please provide an example of a generated ebuild so we can see
what kinds of info it contains?
