This was useful and required in the past, e.g. src:python2.7 does build depend on locales. At some point the build dependency switched from locales to locales-all, at that point debian/locale-gen became obsolete and in environments without "Priotiy: standard" packages installed also non-working. #983305 was for the same issue, removing debian/locale-gen is the proper fix here (dropping allow-stderr might be possible, untested). The same applies to python3.13.
