Sure. In loose order of importance:

 - No rename operation.
 - Slow. Branching and tagging are in particular extremely slow, to
   the point of unacceptability.
 - No disconnected operation.
 - Cannot handle private branches.
 - Has no native support for slave copies of the repository, and
   making our own (as we do) exposes us to assorted bugs and hazards.
 - Anonymous access is a major nuisance to administer.
 - No tree-wide atomic commits.

Not workable - too many of the problems are inherent in the way CVS
manages and thinks about its data.

Also it's (AIUI, never looked inside it myself) not very maintainable.
