Well, I can deal with that... I've certainly got no silly notion that I'm an
Enlightened individual. You should see me after half a dozen margueritas :-)
But... since Karl is the lead, he should get the wrist-slap for not
communicating large changes :-)

Right. Sounds good.

Well, I'm not sure about the term "wanted", but yah... _svr was looking
awfully thin. We can certainly build mod_dav_svn and libsvn_fs, and then
take a look and see if we want to rejigger the line and/or introduce a
middle layer. But at the moment, the two are pretty tightly coupled around
the SVN-FS API.
We have two other code bodies that will want to talk to the FS, and which
may need some functionality that fell into mod_dav_svn:
2) glue wrappers for scripting languages to talk to the FS
Those will probably cause any tweaking of the APIs and/or intro of new APIs.
Previous features of the SVR? Node-level ACLs, and possibly (script/hook)
plugins. With SVR gone, we need new locations for this stuff. mod_dav_svn is
fine, but libsvn_ra_local will need them, too. Maybe these items are sibling
libraries to FS?

:-) ... Ben 'fessed up, too. Thanks for the clarification, guys!
