Seems like LND is hanging up on receiving these messages, even though they're odd :( So, when a peer connects, check if it supplies or wants peer backup (even if it doesn't support both, it shouldn't hang up, and I didn't want to separate the two paths). And when we go to send our own, updated backup, check features before sending. Fixes: ElementsProject#6065 Signed-off-by: Rusty Russell <[email protected]> Changelog-EXPERIMENTAL: `experimental-peer-storage` caused LND to hang up on us, so only send to peers which support it.

Is there a reason to short circuit here rather than in after_staticbackup?

I was aiming for minimal changes. but I pulled this out of the loop. I think you're right, the check could be done earlier..
