I thought nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 would let users bump the fee for RBF-enabled unconfirmed transactions in their GUI. Did I misremember this? Their documentation (mempool.space/docs/faq) doesn't support it and shows no roadmap hints. Anyone else recall hearing this?
