Comment:

 When you say "this happens all the time" and "theme authors get loads of
 support", is there any data to back this up?

 Note that textdomain conflicts are a known limitation ever since we
 introduced just-in-time loading back in WP 4.6. There's really no good
 solution except to avoid reusing the same slugs/domains.

 As for this particular code in question, it should probably be fine to
 simply remove that `is_textdomain_loaded()` check because nowadays we can
 load multiple translation files anyway.
