They obviously think this is more general than those ones they say they won’t do.

As another example, we’ve definitely seen ones that are “homophones” before (I can’t remember the specific example, but think: “there”, “their”, “they’re”), and I think we’ve even seen one as simple as “rhymes”, where all 4 words rhymed with each other. Is that more specific than the ones they said they wouldn’t do? I dunno. I’ve never liked that type of category personally, because yeah, it definitely seems pretty unspecific to me.
