What is textcomma supposed to do? I see that it is defined and used in 
core-mis.mkiv and then redefined in char-def.

My guess is that \textcomma and \textperiod were defined to be 
complementary to \mathcomma and \mathperiod, but this is not consistent 
with rest of the naming convention. (\text... begin text mode commands for 
symbols, and not math mode commands).

Does anyone use \textcomma and \textperiod in math mode? I would suggest 
that we rename them to \puncuationcomma and \punctuationperiod, and add 
\textcomma and \textperiod as text mode commands (and remove the 
definition of \textcomma from core-mis)
