How to get rdeps of _all_ external repositories

[cbullo]

I can't figure out how (or if at all possible) to specify universe_scope for query, so that it returns targets from all external repositories, also the ones generated through module extensions, without the need to explicitly specify them by name.

Example:
bazel query --universe_scope=@data//data:*,@@_main~data_extension~H-1207889251//:*,@@_main~data_extension~H852268376//:* --keep_going 'allrdeps(@@_main~data_extension~H-1207889251//:convert_0)'

So I'd like to know if I can somehow omit @@_main~data_extension~H-1207889251//:*,@@_main~data_extension~H852268376//:* in the scope.

I think I got confused - mixed up deps with rdeps. It seems to list the targets I want even without listing external repos. I'll reopen if it's still not clear to me how it should work.
