Keeping renaming/moving of files and directories straight may be hard
to do, but it is very doable. There is at least one (and probably
more) commercial tool that provides the functionality of allowing a
folder/file to be moved with its history maintained, while still
preserving historically the exact look of what your tree looked like
in the past.
Using a tool with such functionality means that you can change the
directory structure at will with no fear of breaking an old version,
because the structure changes are recorded as part of the history.
I'm not very familiar with CVS, but it appears that this is just a
matter of it lacking a feature that would be nice to have.
Fortunately, I think the current discussion is sufficiently thorough
that we will come up with a future-proof structure, and we won't have
to worry much about restructuring in the future. This means that
CVS's limitations probably won't cause any significant trouble.
