I don’t know. Substitute sources have to authorized before downloaded
substitutes are accepted by the daemon. This authorization happens as
the root user, as it constitutes a system-wide change.
When the daemon is run by the root user to disable substitutes
system-wide, maybe we should not let users override that decision, just
like we don’t let them override from what server binaries are to be
I’m not convinced by the reasoning above, but I’d like to offer this
thought for consideration anyway.

Yes, this is a good idea.
