Probably one to RFC on the devel list before committing lots of code
too, but I think its the sort of thing we could accept.

Doing it in xl would be convenient, but a separate tool might also be
workable. The main point is "don't parse JSON in shell"!

You could also consider implementing a more shell friendly output mode
though, which just produces FOO-separated lines of text with the name
and domid in them...
