If only you'd read the whole post first :)

Yes, I know, I just wanted to flag it up as an idea while the guys were
doing their design work. I'm not sure how it would be implemented, or
configured, they might think a new svn property is worth the effort to
prevent the metadata copy for some files.

I think the benefits may well outweigh the (only?) problem of not being
able to revert a binary while disconnected from the server.
