I believe this idea has been discussed before as "svn diff -q"
functionality. But I don't see any enhancement issue filed for it, so
Nathan if you want to put your writeup in an issue, that would be
great.

To do this right would require some server changes. I don't see
anything obviously incompatible about it, though. Only new clients
could request it; only new servers would be able to send the new kind
of diff. Older servers would send the old kind, and the client could
in that case filter out the unwanted information itself. Kind of
annoying that we'd have to implement it two ways, but it wouldn't be
the first time that's happened.
