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.
