I agree that this seems to be a bit of an oversight.

I think this is a reasonable approach.

I would point out that, per
https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Decoding_table, country
codes AA, Q[M-Z], X[A-Z], and ZZ are permitted for "user assignment".  If
we were to absolutely feel that Etc/UTC needed a place in zone{,1970}.tab,
it would belong there, *not* in GB.  But I don't think that's necessary.
