Another number: I'm answering dozens of support inquiries about
delayed/missing transactions per day. Over the 7 years of Bitcoin
Wallet's existence, I estimate about 50000 inquiries.

On the other hand, I remember only 1 (one) inquiry about the privacy
problems of BIP37 (or privacy at all).

everyone would take it for free, but certainly not if it a) delays
incoming payments or b) quickly eats up your traffic quota.
