As Dmitry has shown, there might be cases Tramp shall not open a new
connection even in this case (called from an idle timer). So we need a
distinction between "it is always blocked to open a new connection" and
"We recommend Tramp to open a new connection only when it is safe for
Tramp". One single value of non-essential doesn't fit this bill.
