Using nonstandard ports would break the `ssh foo.exe.dev` pattern.

This could also have been solved by requiring users to customize their SSH config (coder does this once per machine, and it applies to all workspaces), but I guess the exe.dev guys are going for a "zero-config, works anywhere" experience.

Zero-config usually means the complexity got shoved somewhere less visible. An SSH config is fine for one box, but with a pile of ephemeral workspaces it turns into stale cruft fast and half the entries is for hosts you forgot existed.

The port issue is also boringly practical. A lot of corp envs treat 22 as blessed and anything else as a ticket, so baking the routing into the name is ugly but I can see why they picked it, even if the protocool should have had a target name from day one.

-p ?
