Yes, a paper is provided. However, when I asked for a usecase I really did mean:
"is anyone going to actually use this?". Which is a very non-trivial question to
answer, particularly when it comes to "space stuff" (how commonly is linux even
used for those?).

Good answers (IMHO):
- "Yes, we have a couple of planned users for this"
- "Yes, this has been maintained out-of-tree for X months/years, known to work
well for a variety of users"
- "Yes, we are using it"

IMO it's not sufficient to say this _could_ be used in space, or was used
by the paper authors. And instead of a straight up answer, there was radio
silence.
