Even in English, the use of it as an adjective for anything except personal identity (specifically, a way to identify personal ethnic identity in a way which was inclusive of non-binary gender identity) seems to be a step detached from its original origin taken by media adopters who just do a global find and replace to swap it for Latino and/or Latina without considering context.

Not quite on the level of an American college newspaper I saw in the 1990s that identified Winnie Mandela as an African-American speaker when she was making an appearance, but the same kind of process.
