Resolved for some users, not for all. The underlying trade-off will
always be there; less bandwidth makes it harder, more addresses to check
makes it harder; an HD wallet used properly without re-using addresses
will quickly lead to a fairly full bloom filter unless addresses are
expired, and expiration leads to scenarios where funds can be lost.
I think we need to provide users with better options than that.
