I think we're looking at the wrong thing.  The root problem is what we're
warning about, not that the warning is being printed.  It doesn't make
sense to warn about the inherent nature of things.  When peole create a
linear LV, we don't print a warning that it's not redundant.  By warning
that the pool is overprovisioned, we also mislead people into thinking
that this is what they should worry about, when in fact it's free space in
the pool which is the real thing to worry about.  So I think the message
should be dropped and replaced with something more useful.
