I don't see how this is preferable. We'll still need to keep that third repository in-sync.

FWIW this repository is ~always in sync. Annoying, yes, but this shouldn't be an issue. We could also have a repo that's more automated.

I think at the time Joost tested it lightningdevkit/rust-lightning#4370 wasn't merged. I then went reviewed and landed that PR, bumped bitcoin-payment-instructions, opened the other PR, and asked him to review so we can be unblocked, as he in particular was held up today due to LDK's API breaks. IMO it shows once more that we need to go back to the drawing board on depedency mgmt and merge policy. Maybe we need a hard CI check in LDK that requires fixes are up before we merge any breaking change.

Hmm, should still have worked. the Commit here was the top commit on that PR, rather than the future merge commit. I think it was just a git oddity hitting an nginx max request body size issue.

As for the general issue, I'm a bit confused why someone was blocked on an update to LDK Node syncing to two trivial upstream PRs? Testing against upstream without those PRs should have been pretty easy, and waiting a day for the update doesn't seem like an issue to me.

But, either way, the limitation in this case wasn't a desire for rust-lightning devs to update LDK Node, but rather that it currently requires you to do something on your bitcoin-payment-instructions fork, which means you're the only one who actually can update LDK Node.

I wonder if we can't automate that part - just have a git repo that maintains a bitcoin-payment-instructions that gets its Cargo.toml auto-updated (as long as no API changes have impacted it) and maintains branches for the last few week's worth of commits to rust-lightning so that there's always a commit to point to.
