Bug#844725: libproj12 should conflict with libproj9

[Gianfranco Costamagna]

Hi,

because the testsuite is not ran by default against every "proposed" package,
but against release pocket
(you can call them testing and unstable if you like)
This is done because we want to test the single change, not against something huge that
might have a lot of regressions or ongoing transitions.

same as above, to see regressions usually the best way is to restrict changes
to the bare minimum

rebuilds are complete, to migrate it still needs some other transitions to finish.
-release is ok with the old library
-proposed is ok with the new library.
So, the transition is finished, but needs migration because of something else.

they can cope with this one.

this is true, I hope I don't get autoremovals because of this, even if
release acked special unblocks for them :)
(it would have been unfair otherwise)

>Why is libproj9 still being pulled in via the dependencies?


because of testsuite confined to -release

I don't see any mysql-workbench here, anyhow, the reason for it not migrating is:
some rebuilds are still ongoing (for other entangled transitions), some architectures
needs fix/removals/decruft for other stuff
