But you draw the wrong conclusions. I already told you that hamm is not
released. If there are many severe problems with the upgrade from category
three above *after* we release hamm, I'm happy to agree with you.

Those are bugs, please report them (please don't report when directories are
left --- this bug is known and reported multiple times. It is so old, you
can almost call it a feature :)

There is the package "cruft" in slink, which will compare dpkg's databases
with the installed files and print the differences (taking a lot of further
input into account).

Those are two different things. Please read again my note about "hamm is not
released yet". But read also below about exceptions.

Oh well, write it on a poster and stick it on a wall: I made a too extreme
statement. For the record:
"There are cases were a reinstall is better than an update. If this is the
result of a problem in the Debian distribution, please report it as a bug."
Satisfied?
In my opinion, a few directories left over do not warrant a reinstall. YMMV.

Ok.
