Sounds reasonable in general.

`org-export-with-latex' is a global setting. I do not think that texinfo
equivalent should be global. It should only be declared inside
ox-texinfo.

As for the default value, it would be better if the option were set
depending on the installed Texinfo version. If the installed Texinfo
supports math, set it to t. Otherwise, nil. Of course, users will be
able to override the default as they wish.

Best,
