.... Right -- "temporary_channel_failure" -- here https://github.com/lightning/bolts/blob/2b9c73b48c1920df8e7e867d110fab2d720a059b/04-onion-routing.md?plain=1#L1157 .
The issue is that hitting failures like this has the effect of increasing payment latency for users, and also, if there are too many failures, the payment will time out entirely. Shouldn't we, for the sake of users, be trying to insulate payers from potential failures?
And ....isn't a good way to do THAT is to simply signal to the network "hey, don't use this channel in this direction, I'm signaling this by putting my fees high"..... ?
