Hmmm... if I remember the original discussion on the PR that added this
code, I chose not to do it to avoid breaking people who might have these
references in their configs even though the code wasn't doing substitution.
It might be a good idea to do substitution for all config entries,
registered or not, but I'd rather do that in a separate change (and then this
private API could be removed).
