Great that you looked into it. That’s something we did not explicitly
address until now, on the grounds that ‘guix substitute’ would typically
look up both a store item and its dependencies, which in practice means
that the TTL of a store item and that of its dependencies would likely
be synchronized. But clearly, it’s best to ensure that by construction.

I think keeping both is ideal, notably from a fault-tolerance viewpoint.

Definitely; this should be high-priority for the project.
Thanks!
