tl;dr: I have a Libre Relay prototype available for testing. It does three things:

1. Removes the OP_Return limits.

2. Connects to an additional four Libre Relay nodes, to ensure transactions propagate.

2. Implements pure replace-by-fee-rate (RBFR) and full-rbf, to solve Rule #3 transaction pinning.

I'm already running it on a few mainnet and testnet nodes. The combination of #1 and #3 is interesting, because an objection to RBFR is it makes possible certain expensive DoS attacks. And #1 should piss off some people... So we'll see if the DoS attacks are serious enough that those pissed off people actually attack it. 😁

I have limited understanding of what is going on here, but am trying to learn more. I appreciate developers like yourself making it possible for less technical node runners like myself to exercise their right to "vote" by running the node software they choose. Thank you! Now for an option on my #Start9 (;
