So then we do agree.

This is where we disagree: I think it would be best if we leave this
choice to the user.  I do not think it is possible to come up with a
"one size fits all" solution that works across all the handlers.  We
could leave the job of deciding the "most appropriate format" to the
major-mode but I am afraid it will only produce even more user options
which would be too chaotic to manage.
