unicode-math Scale= option to \setmathfont undocumented

According to several answers on tex.SE as well as issues here, there is a Scale= option to \setmathfont. However, there is no description of this options and its possible values in the user manual as of 2019/09/26. I think this information should be added.

unicode-math will simply pass all these options to fontspec, and they are documented in fontspec package.

Hm, alright. After searching specifically for fontspec, I found the following sentence at the end of the introductory paragraph of "4 Unicode maths font setup":

Other fontspec features are also valid.

So you are right, it is documented.

I still wish it would be more prominent. After reading a package documentation once (more or less) completely, I often try to quickly find the feature I want to use by searching the pdf. In this case, searching for "scale" finds appendix D on XeTeX math font dimensions.

Maybe it would be possible to have a table / appendix briefly listing the fontspec options, and refer to it from that sentence?
