Ah, good point.  Anything that wants to enumerate the subkeys under
remote. hierarchy MUST be aware of the new convention.

So such a code must of course need to be updated to treat "*" as a
virtual thing and exclude from enumeration (I suspect "git remote"
has the same property), and delivered to the end-users at the same
time.

An alternative is to use remote.<key> as a fallback default for
remote.<name>.<key>, which has been done successfully for other
hierarchies like http.<url>.<key> would override http.<key> for any
defined <key>s.  So if we have remote.<name>.skipFetchAll per
remote, we could use remote.skipFetchAll as its fallback default
value.
