[Just translating between english and english here -JimC]
Seems clear here. If the variable is nil tramp will be happy to do
user-interactive stuff, such as prompting the user for a password.
But tramp would prefer that the variable be set to non-nil in any
function which does remote work which will not require such user-
interaction.

I think you are thinking about it the wrong way -- or at least
sufficiently differently than the authors as to fail to see their
meaning. (Please do not take that as a flame.)
Don't think "importance" but rather "will this require user interaction
to succeed?".
And set to nil if it will require user interaction to succeed.
