That did not occur to me when drafting the proposed change. I'm not
opposed to such a change, but I don't see much potential for ever taking
advantage of it either. I can see some potential for allowing names from
other character naming sources (as previously discussed with P2071
<https://wg21.link/p2071>), but I don't think '{' or '}' are currently
used in any common character name sources. If motivation arises, I
suspect the concern can be addressed then with minimal churn.
