Resending due to ML bugs....
On a related note, it would be nice to get some clarity on appropriate
usage of the r= field here.
The way I had implemented it initially was that if an invoice had an r=
field any publicly-discovered last-hop routes would be ignored as the r=
data is most likely more up-to-date than any public route rumor information.
However, if it's only used as a hint and only one or two out of
potentially many channels are included in it, that may make little sense.
Not really sure what the appropriate guidance should be, probably
something like SHOULD prefer to use invoice-r=-provided-hints over
publicly-discovered routes however MAY use other last-hops in case a
substantially better route is known?
