I completely agree.

What exactly would the new policy be? Is it just the last component that
is bumped, or is the version number bumped according to the PvP? Is the
version bump relative to what was in the repo before, so after the
1.2.0.1 directory release we might have 1.3.0.0, 1.4.0.0 and 1.5.0.0 in
the repo before 1.5.0.0 is release, skipping 1.3 and 1.4? Or do you
check what the last release was and only bump if necessary relative to
that (so once the repo reaches 1.3.0.0 it will not be bumped further
until a release is made)?

What I usually do is to bump the version every time I want to depend on the new library in another app (even if it is not released),

and simply skip release numbers. I usually do the version increases according to the PvP.

Would we also follow this policy for packages we don't maintain (perhaps
with ghc-only version bumps if necessary)?

I think that it is a good idea to do this too, but it is probably better to use a different versioning schema (e.g. something like package-1.1-ghc) , as these

versions are likely to be temporary, until the changes propagate upstream.
