By the way, what version of cvs2svn were you using? The one from the
Subversion 1.0.0 tarball, or the very latest from cvs2svn.tigris.org?
If you weren't using the latest, try again; cvs2svn is improving at a
very rapid rate.

Heh. Nope :-).
It's like saying that Win32 executable compatibility is part of the
Linux kernel's "requirements" simply because many new users expect to
be able to run Windows programs under Linux. The WINE project came
along and solved it, but if they hadn't, would you blame Linus and
friends for not supplying it?
In general, you wouldn't expect *every* revision control system to be
able to convert history from every other system, would you? Sure, you
might expect that Subversion would convert CVS history, because SVN is
designed specifically to replace CVS. But we don't consider that
conversion a feature of Subversion, by the following logic: anyone
starting a new project would *never* need that feature.
Many people start projects from scratch, instead of migrating existing
data. So Subversion is *quite* useful without a finished converter.
Another way to look at it is: why not expect the CVS project to supply
the converter, instead of SVN? Subversion has existed for the same
amount of time for both projects, after all. Of course, you don't
expect to find the converter at cvshome.org, but analyzing *why* you
don't expect that might be interesting...
