Which IMHO clearly says "you may prefer downgrades over removals".

I'd don't consider this "grave" at all, as it neither "makes the
package in question unusable or mostly so", nor "causes data loss",
nor "introduces a security hole allowing access to the accounts of
users who use the package". And I've only used "important" instead of
your initial severity estimation because the downgrade seems to have
been unnecessary.

I though never ran into that issue (despite having
Aptitude::ProblemResolver::Remove-Level set to "maximum" which should
have a very similar effect), so I assume that possible further
non-default settings could have caused this. Please post all your
Aptitude resolver related settings (or confirm that the above
mentioned setting is the only one).
