Then why didn't we bump libc multiple times in a branch? It's the same
exact thing except more fine-grained. If it's ok to bump symbol
versions multiple times (remember, we've already done 1 bump by adding
versioning and going to libc.so.7) in a branch, then it should have been
ok to bump libc major numbers multiple times.
I agree with Dan that we are trying to build releases, and folks running
-current are expected to tolerate change during the current branch.
I wouldn't expect more users until we actually do release BETA1, so I
would go ahead and commit the new fts(3) soon so it is in BETA1 and
the RELENG_7 branch when it is branched.

I think it will be confusing to have missing symbols just as folks would
have thought it confusing to have 6.x ship with libc.so.8 if we had
bumped libc multiple times. I also think that just managing the
interfaces that show up in releases and -stable branches will be enough
extra bookkeeping to keep track of as it is.
