Thinking about this again, since updaters typically returns actual
versions (tags) instead of commits, how much would such a
feature be used?

OTOH, I could definitely see use for an ability to update packages like
these to proper versions (removing the surrounding 'let') but that's
probably more rare and may not be worth the implementation effort.
