I, for one, think we shouldn't.  But I won't mind it, if that means
having a good, familiar, promiment, those-really-are-the-mathing-parts,
default for the 'flex' and 'substring' styles.

My personal bikeshedding proposal goes in this direction.  We can
later enhance it by convincing 'prefix' users that it's just as
explanatory to have the common part prominent and the first difference
un-prominent.  Then there won't be much of a dissonance.

But I liked any of your initial proposals, too, Stefan.  They are just
as trivial and also scratch my back--shed.  Also Juri seemed to
suggest something in consonance with it at some point.

And if Dmitry wants to push new defaults, I'm behind him, too.
