What

The channels-unavailable banner has a case for connections whose protocol era has no channel delivery path.

Details
  • the notice is keyed per server name, so several such servers each raise their own notice
  • sits alongside the existing channels-unavailable reasons
Evidence

this connection's protocol version has no channel delivery path

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
