 Replying to [comment:58 jeffstieler]:
 > It would be difficult to check for fields after this filter.. should we
 expect a filter on `'posts_request'` to know the pitfalls and modify the
 query accordingly so it can still be optimized?

 I think so. Using posts_request is inherently fragile, so the code in
 question should be very resilient.

 On the other hand, maybe it's worth introducing an 'expand_ids' query var
 that forces {{{$expand_ids = false}}}.
