well if an author is coding directly in mathml probably wouldn't have 
the mstyle.
If you're converting from TeX code (that is not using \mathchoice) then
you would need that for absolute fidelity, although to be honest often
if tex alignments end up being used in a subscript the author _doesn't
want the table to stay using large fonts, and ammends the code to use 
mathchoice so it gets smaller.

again, if tex did this you probably wouldn't find it strange:-)

 From the speed you may note that it was a personal response, but I 
think I only cited what the spec is saying:-)
