 ## Problem
 
-`git.remotes.*.ExtraHosts` is currently the available mechanism for steering

-useful when the gate itself needs hosts-file resolution, but it is the wrong
-tool for ordinary SSH client aliasing.
+`git.remotes` currently mixes repository identity, SSH key material, known host

+awkward: it is a hosts-file override, but the Gitea remote case really needs SSH
+client config and host key verification.
