11.67.1.4 Fix integral lower bound kerning in textstyle or smaller with unicode-math

https://tex.stackexchange.com/landing/r/digest?cta=question&id=751706

When using unicode math, the lower bound of the integrals is very close to the integral symbol, see this example

11.67.1.5 Why is \l_keys_choice_tl a token list instead of a string variable?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=751811

Question: Why is \l_keys_choice_tl in l3keys a tl instead of a str variable? 
My understanding is that key names are stored as strings using \tl_to_str:n. For choice keys, each choice is implemented as ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=751725

It is well known that math versions and ranges cannot be combined with unicode-math. However, for my document, I want to mix different fonts and still switch between two major modes (versions) of math ...
