That would mean to go back to ancient times where things were not 
authentic, and the system generally not very well-defined.  We've left 
this behind a long time ago.

I did not look through the list of issues in detail yet (I will do that 
later), but it is probably just a recurrence of what we knew already when 
the generic interpretation mechanism was made formal and "size" became its 
main application -- based on older less formal mechanisms.
