20.16 “Customized Options” is how this is labelled in the documentation.

I’m doubting that mentioning customized variables everywhere in the
documentation besides the chapter that explains that they (and all other
settings) exist is a benefit.

Usually just post concrete ideas to -hackers or -bugs, or even -docs.  The
good ones tend to get implemented even without a patch of the sgml

There is also existing material out there on contributing patches, it
