Subversion should merge with Mercurial (reverse takeover)

I've been nudged by nice people to post this here - honest !!

I'm a user of Subversion from about 0.7 onwards (via Codehaus). I was at
the 1.0 party in Brisbane, CA many tears ago. Like Perforce, Svn is still
out in front *for a couple of features*. One that is fascinating for me is
composite checkout (sparse directories for you, client spec for Perforce).
Google uses the hell out of
that<http://paulhammant.com/2014/01/06/googlers-subset-their-trunk/>,
but Facebook don't. I compared the two companies a few weeks
ago<http://paulhammant.com/2014/01/08/googles-vs-facebooks-trunk-based-development/>.
Mercurial does not have a sparse-direcories feature that you could use to
simulate a composite checkout. Not does it have, by default, fine grained
permission on directories (incl branches). Thus, if y'all were to consider
a merger of sorts, Mercurial does not yet have a superset of Svn features.

Discuss :)
