I didn't mean to be offensive.  I meant it more in the sense of "you
deserve to expect more from your software".

The Git test suite (tests t/t960?-*.sh) demonstrates some of the known
problems with cvsimport, and those failures are summarized in the
manpage for git-cvsimport(1).  Not all of the problems are related to
branches and tags.  There might be more problems; I simply documented a
few that I found relatively quickly then I stopped looking.

There are benefits to the split blobfile/dumpfile approach for some
users, so I wouldn't want to get rid of that possibility.  But there's
no reason I wouldn't accept a patch that provides an option to convert
as you describe.  Alternately, it would take only a few lines of script
to automate it yourself.
