I'm minus-several on this bit, because that is a solved problem and
we really don't need to introduce More Than One Way To Do It. The
intention has always been that get_relation_info_hook can editorialize
on the rel's indexlist by removing entries (or adding fake ones,
in the case of hypothetical-index extensions). For that matter,
if you really want to do it by modifying the IndexInfo rather than
deleting it from the list, that's already possible: just set
indexinfo->hypothetical = true.
