So many groff discussions get re-routed to TUHS thanks to Doug's MUA. :)

This would tighten the existing semantics of %O, would it not? Maybe
that's not a problem, since it's already defined as a dumping ground[1].
So if I understand you and the GNU refer(1) manual correctly, %O would
be parsed for a pair of brackets[2] containing keywords only (no
fields), and if that resolved to a single reference, the label for that
reference would be interpolated. That of itself would be sufficient to
halt the recursion.
Here's an example of what this sort of thing looks like today, _without_
adding this feature to %O[3].
