We have no thoughts on 2.0 at all. That would break compatibility with
a huge ecosystem of tools built upon Subversion. Nobody wants to rock
the boat that hard, and I don't think it would really be all that
great for end-users losing much of their toolset that way.

We could, yes. The problem is that we store changes differently from
CVS. There is no simple "it changed N lines and added N lines" for a
given change (because we do binary deltas -- character by character;
we'd have to reconstruct files to detect line-based changes). CVS does
this file by file, but we'd want to summarize the whole revision, so
we'd have to total these deltas across all files touched by the
commit.

Doable, yes. But some non-trivial work to reproduce.
