Without having read the code I'd have very much expected a
"remote.*.skipFetchAll" to impact:

    git fetch --all

Or:

    git remote update --all # --all does not exist yet

As e.g. remote.<name>.skipDefaultUpdate would do (i.e. impact "git
remote update" ...).

I suspect naming it like this started as a hack around the lack of
4-level .ini config keys, i.e. so we could do:

    maintenance.remote.<name>.skipFetchAll = true

But I wonder if we couldn't give this a less confusing name still, even
the pseudo-command form of:

    maintenanceRemote.<name>.skipFetchAll = true

Or something...
