The biggest problem for 'normal' users using these (or other) snapshots
is the potential working copy incompatibilities between versions. I've
been caught numerous times saying "oh crap", after I mistakenly updated
a large working copy with a dev version of subversion.
Maybe the wc-ng stuff can help by making things more forwards and
backwards compatible, but I doubt that is even on the list of things
to address.
Don't get me wrong, I think nightly builds are a great idea, just
we can't expect people to consistently use them unless working
copy compatibility is enhanced.
