My kneejerk reaction is that I'm hoping for future Subversion working
copies to be more discrete than current ones, not less so, and my
design goals for a WC rewrite would be to explicitly disallow
multiple-WC operations. So I'm not inclined to focus too much on
making multi-WC operations work better... But that may just be me.
