You first have to think ;-).

I would say there are two kinds of users.

 - To the simplistic ones who fear the power of configuration, we
   can simply tell "You don't. Use 'single' when you want to keep
   working with the single branch. If you want full, reclone, and
   migrate your work from the single one by fetching from it to the
   full clone before discarding the single one".

 - To the ones who wants to take the full advantage of flexibility
   of configuration, we can tell "remotes.$name.fetch configuration
   is your friend. Do whatever you want to do with it, but here are
   two hints".  The hints would cover the case to revert to the
   default refspec, and the case to add another specific branch.

These days, with "git config" and "git remote" wrappers, I do not
particularly see a need to fear the power of configuration, though.
