I think you mean they don't resume at all, so you therefore don't know

I think what you are saying is that resume is harder than powering up
only for UP, since at resume time we might have per-peer state to push
into the key cache. When bringing an interface UP, there shouldn't be
any such state since and up->down transition presumably clears the
I don't see how AP mode avoids the losing wep keys when powered down
I'm using ibss mode, for what that's worth.
