For example when we require any script to act as super script as in symbols for upper limit and lower limit in summation, or let us say 2^(2^(2^2)) were the 2 must apply 3 levels of superscript styling. Also the symbols like integration and summation must have some kind of place holders to depict these upper and lower limits. extendable natural horizontal line for separating numerator and denominator part of a fractional equation. Right now we might have to do away with (/) symbol. The same case with nth root; the horizontal line must cover the equation from the above completely. Right now we do away with (√ ∛√) There are numerous such examples. Some of these demerits can be easily removed while others may require careful thinking. These need to be removed gradually by Unicode consortium, provided some agency works on it. Also the font based mechanisms of latex could be incorporated, but in order for rendering engine to take such decisions, such instructions need to be provided to them. And incorporating specialized code points like \Ux200C and \Ux200D to do these might suffice to some extent. I will try and highlight these things in the white paper.
