This seems like something that might be better dealt with by modifying the RBF eviction policy to calculate feerate separation between the transactions in the mempool and opportunistically evict the sweep transaction+parent if it has a sufficiently different feerate from the bumped fee

This isn't BIP material, as it merely describes a local policy. (BIP125 itself is also local policy, but one that involves standardisation since it expresses how wallets interoperate with nodes with that policy.) If you wish to suggest this policy change, you should just implement it and open

==Abstract== BIP125 allows transactions to opt into replaceability with a primary use case of allowing users to increase the fees of unconfirming transactions, helping create a more efficient fee market place. However this goal is hindered when the receiver of a transaction spends from the
