I agree with your preference.
Ignoring shell quoting in glob bracket patterns means removing a useful
feature: the ability to pass an arbitrary string of characters in a
parameter, one of which is to be matched.
OTOH, honouring shell quoting in glob bracket patterns does not remove
any functionality, as you can simply not quote the expansion (which is
safe, as it is not subject to split or glob in that context).
So if this is indeed not specified, I think the standard ought to be
amended to specify the current majority behaviour (everything but ksh93).
