I don't see how to have a more precise similarity without having the
number of entries registered by the indexed value somewhere.

I think it can be interesting for other flavours of GIN usage. Is
there a way to add the number of entries of the considered indexed
item to the consistent prototype without adding too much overhead and
complexity?
