Block Batch Filters draft :

BIP 157 unlike BIP 37 not allow apply filters to mempool and check zero =
confirmation transactions.
Light client that refused to use BIP 37 due to privacy leaks can process =
unconfirmed transactions only one way and this is loading the entire =
mempool transaction flow.
Mempool Transaction Filters draft:

Summary:
- improved Block Batch Filters definition
- unlocked ability to filter unconfirmed transaction for SPV nodes =
used BIP 157 instead of BIP 37 due privacy leak in BIP 37
- more bandwidth consumption reduced in contrast with block filters =
and downloading full blocks for affected addresses
- proposal for future consensus layer soft-fork to make block =
filters commitment one of the block validation rule to protect light =
nodes from payment hiding attack
