To be clearer: I mean I don't see any obvious ARIA mapping for suggested labels
for a range control.

Maybe. I'd be happy to expose both bits of information and let UAs (including
AT) expose them to the user as they feel is most appropriate.

The value of the option element in the list is always an actual range value.

Sorry, I mean "should" as in: this information *should* be included, but it is
not yet.
