Let's Encrypt Integration for HTTPS certificates
It should be possible to define a list of SSL hostnames. Application Gateway should automatically acquire and renew certificates for all given hostnames (most probably through the HTTP domain validation process).
For every request, Application Gateway should use the correct certificate based on the hostname.
Supporting multiple hostnames is critical to use Let's Encrypt with multi-site routing.
This is on our long term roadmap.

Long term enough for a replacement to have surfaced.
Should probably consider doing the same for Azure Front Door now as well :D

Must be on the same "roadmap" as Wildcard on the listeners...
