And also would require new code on svn's side to be written.

There are, though, deduplicating filesystems, that store a file just
once if there are several copies of it. That means a file and its
pristine won't consume twice the platter space, assuming the file
doesn't use either svn:keywords or svn:eol-style=native.

(I'm thinking of zfs. And BTW, the pristine store also deduplicates, so
if two pristines have the same sha1, they're stored just once.)
