IMO there should be placeholder text explaining that we used to have a service there but it was removed (with a link to this issue), along with some guidance on why sites might wish to keep it around (if at all).
Let's do a favour to future us and any client doing an upgrade to help explain within the manifests why something is different rather than having to answer it one-off via support tickets.
