We could try and do that.

The proposal is about pulling up the bottom end on the hadoop's we
will run on going forward.  If all hadoop's from 1.0.0 on have
security, and we can depend on that being the case going forward, then
we could do things like ship a single artifact rather than the two we
currently ship; one that does not depend on a secure hadoop and
another that requires it.

I forgot that 0.22 hadoop doesn't have security.  Would suggest that
we drop support for it too in 0.96 hbase.
