   Is there a Rescinded status given that its now off-by-default and really shouldn’t be used?

   ACK

   Per BIP 2, Withdrawn only follows from Draft, where I would argue here that this BIP should have long been Final. From Final something would only be updated to Replaced or Obsolete. In this case, I think that some Bitcoin implementations still serve BIP 37 and previously it was argued that BIP 37 should remain in Final for that reason, so perhaps the same applies here.

   Sure, LGTM. Whatever status y’all think makes the most sense.

   Obsolete makes sense to me. The replacement for bloom filters is compact block filters, which does ~everything they did but better.

   Thanks all for the feedback.

   • Bitcoin Core still has support for BIPs 37 and 111 (e.g., via the -peerbloomfilters config option) and both BIPs are currently listed as implemented in https://github.com/bitcoin/bitcoin/blob/8ee8a951c205c5365f7557253b8fffc12e6e670c/doc/bips.md.

   • Many bitcoind nodes still signal NODE_BLOOM.

   • BIP 37 has Final status.

   Given these, (for now) it seems that BIP111 should be Final.

   At some point, perhaps when support is removed, they can be marked as Replaced or Obsolete and the BIP 152 header updated to indicate that it replaces them.

    I think “Final” is correct for the time being.
