I haven't seen that, but I don't really see how that's related - your
post is about indexes, mine is about building temporary bloom filters
when executing hash joins.
FWIW, I think bloom filters should be easy to add to BRIN indexes, as
another type of 'summary'. That should address most of the missing
pieces in your implementation (e.g. WAL).
