  | Yes, that's what I said. In the current scope, unset arranges for the
  | variable to appear unset. In a previous scope, unset just removes the
  | variable, which uncovers an instance of the variable at a (further)
  | previous scope.

Were I you, I would simply change the "in a previous scope" behaviour to
match the "in the current scope" behaviour.   That makes it consistent,
and rational.

I cannot believe that there is anything anywhere which depends upon the
current weirdness.

I'd also forget "remove" as anything that unset is supposed to achieve,
and I would change "appear" to "be" in the description of the current scope
