There are a handful of contexts where it makes more sense, like for a HR person potentially, without trying to bring ideology into it that's the place it makes sense since that's the place where you can actually implement the concepts.

There are contexts where it is mandatory but makes no sense, like NSF Fellowship Applications where they're asking someone who is just finishing an undergraduate degree and is proposing a research project that ends in a PhD -- who has effectively no influence on hiring or even culture really, and is supposed to focus on the technical aspects and personal aspects of who they are. There are things you can fit in there, but let's say the mandatory question is worded so confusingly that it is hard to even guess what to write about. What, you're going to hire people to assist you in your research under DEI principles when you have no control over the budget? It's just confusing for someone in that position.

Staff hiring? That kind of makes more sense honestly, trying to be non-ideological here. Those people can actually hire people and create a culture that is either DEI positive or not, whatever you believe about whether they should.
