That's OK.  I'm only talking about the intended meaning of
non-essential, independently of any particular use such as in Tramp.
If there's a risk of problems and non-essential is non-nil, then don't
open a new connection.  If there's always such a risk, then never open
a new connection (when non-essential is non-nil).
