Aha, so it _is_ the map regexp and the rewrite regexp mutually interfering! Thanks for the speedy insight.
Looking through the comments in the ticket, I agree with you that 'the current behaviour is bad, and should be fixed'. If only on a principle of least surprise.
Until it is fixed, however, it would be extremely useful if, in the description of the 'map' stanza (ie, in <https://nginx.org/en/docs/http/ngx_http_map_module.html>) it mentioned that the regexp in 'map' can interfere with the regexp in a 'rewrite' directive, in such a way that positional groups in the latter don't work. It could note that this is a (temporary?) defect, but that until it is fixed, using named groups in the 'rewrite' regexp is a good workaround, and give an example.
It would be better here than in the documentation of 'rewrite', as that would keep the 'rewrite' documentation relatively simple. It only needs to be seen by people using 'rewrite' and 'map' together, who might be assumed to be marginally more sophisticated users.
