1> Feasibility. Not all of arch's semantics can be implemented in a CVS
repository -- atomic commits, for instance -- while keeping the contents
of the repository something that traditional CVS users still find
useful;  effectively, to maintain arch's useful semantics, you'd have to
make arch into another metacvs.

2> Performance.  Should you  decide to keep compatibility with
traditional (non-metacvs-like) layouts, a lot of operations which are
O(1) in arch suddenly become at least O(n) under your proposition, n
being the total number of files in the repository.

I'm sure there are other issues as well, but these are the first two
that come to mind for my non-guru self.
