There was a long discussion on cfe-dev about this issue approximately January-February 2020 including @scanon @andrew.w.kaylor and many others.  While there wasn't 100% consensus to move to ffp-contract=on there are many reasons to do it including better numerical results and debuggability.  I'm hoping that @andrew.w.kaylor @kbsmith1 @rjmccall and others will join in here.
