Peter,
An important use of the core is being border router to proprietary =
software, that is usually indexing the block chain and mempool. That =
software is also assuming that double spends are not relayed by the =
core.
To remain useful as border router, the replace-by-fee patched core =
should only relay double spend if it actually replaces an earlier =
transaction, as otherwise the replace logic that is according to your =
commit more than just fee comparison, would have to be replicated in the =
proprietary stack and mempool might get out of sync with that of the =
border router.=20
