Sorry to jump into this thread at a random point.
There's another aspect to this discussion that hasn't been brought up.
Imagine that I release a package bar-1.0.0.0, that depends on:
build-depends: base, foo >= 1.1
Then, suppose foo-1.2 is released and bar-1.0.0.0 is incompatible. If you
simply release a new version of bar with a stricter upper bound, cabal may
decide to install the original bar-1.0.0.0 together with foo-1.2, which
will lead to a broken build. Blackling the package is the theoretical
solution to this problem, but may not work correctly[1]. However, by
overwriting the original cabal file with a tweaked one, cabal will be able
to make a more sensible decision.
I'm not trying to advocate anything in particular here, just point out an
aspect of the discussion that I think has been missed.

Hi Lennart,
Bumping [the (n+1)th digit] is not safe, as the maintainer might decide to publish a new version that adds a new component.)
Suppose I publish foo-1.0. Then a sequence of edits would produce versions 1.0.1, 1.0.1.1, 1.0.1.1.1, and so on.
Why would there be any problem?
Best regards, Peter
