Curious: if you're not worried about people accidentally using old CVS
tools, then why try for backwards compatibility?

To answer your actual question: we have to keep track of a lot more
data than CVS working copies keep track of. We have to cache changes
to the tree structure until they're committed, file/dir/dirent
properties, etc. We can probably use "Root" and "Repository" files,
but even if we called some file "Entries" it would still have to hold
different data from what the old CVS Entries file holds (for example,
sticky tags and branches don't happen the same way).
