I'm in a similar position -- I don't have any use cases for IGNORED
myself right now, so I'm just trying to guess from what I've seen
people say.

Just having where= around makes it at least possible, if cumbersome,
to handle one of the big problems -- working with subsets of large
datasets without having to make a copy. It's possible we should leave
IGNORED support alone until people have more experience with where=,
and can say what kind of convenience features would be useful. Or
maybe we can get some experts to speak up... perhaps this will help:
