I've always done it that way.

Just s/wheezy/jessie/ instead of both gives sysvinit-core.

That is the case.

I wasn't sure which package was the cause of it and where the fix should
be. I probably should have filed it against the whole set of packages
involved until the location for the fix is found. Please feel free to
reassign as appropriate.

The issue doesn't happen with aptitude dist-upgrade, it only happens
with aptitude upgrade.

Whether or not one should use aptitude flips around between releases so
I believe people will be using it whether or not we recommend it for a
particular release.

I expect people will just use the tool they prefer and won't read the
release notes. I note that one problematic command is 'aptitude upgrade'
and the "Minimal system upgrade" section doesn't mention not using
aptitude. I've filed #780076 about that.
