With that patch people are still free to choose to provide bloom filtering
services by setting -peerbloomfilters=1

There really isn't due to sybil attacks; we already have good reason to believe
that the Bitcoin network is subject to them by deanonymization/chainanalysis
services.

Indeed there's a good argument that creating services that are vulnerable to
sybil attacks encourages them by making them succesful at something. That
creates its own risks, for instance the risk that the sybil attacker will
themselves screw up and cause a bunch of nodes to go offline at once.
