There are at least 30 different operators that would require similar markup,
following this line one will have to introduce separate elements for all of them.

What is the point is restricting scope of markup in this manner. 
Do you think that some of the features in current proposal that are omitted here are
not realistic? If so why?

Excluding Ruby (and partly markup for sums, products and similar stuff).
