I consider it to be quite mature.

I don't have any exact details on what has been tested. I have tested
these with multiple APs, but not with Aruba, and I have heard of number
of other people having used these features successfully. I'm not aware
of any bugs. Yes, opportunistic key caching is supported, but not very
throughly tested (or well, at least I haven't done much testing for it).
