openssh-server (non-pam) is installed and can't be removed

Even though postmarketos-base-ui pulls in openssh-server-pam, and nothing in pmaports seems to depend on the non-pam version, it still seems to be installed and can't be removed:

; sudo apk del openssh-server
World updated, but the following packages are not removed due to:
  openssh-server: postmarketos-base postmarketos-ui-gnome flatpak
                  device-postmarketos-trailblazer

After this operation, 0 B of additional disk space will be used.
OK: 8050 MiB in 2130 packages

Nothing stands out in the APKBUILD to me that explain this. And afaict we shouldn't be installing this.

cc @craftyguy who seems to love packaging bugs :P
