Mand'oa as far as I can tell is roughly an English relex.
I know that many folk feel that relexes are aesthetically bad, but that is, imho, separate from what counts as topicality.
I agree that relexes are roughly coded English. But where else would one ask about Mand'oa, this fandom thing that Star Wars fans engage in that outwardly looks like what the Elivish or Klingon fans do, but lacks a sufficiently distinct grammar and lexicon to be isolated from accusations of being a relex? You can't ask a Mand'oa question on the English SE on the grounds that Mand'oa is just coded English.
I'm asking about this specific language, not just whatever whatever.
