It seems to me that the region of the page excluding the margins is a
meaningful concept that a user may wish to specify, and thus the existing
@pagesizes command may be useful and should be kept with its current
behaviour.  If it was the case that people needed to specify arbitrary
paper sizes then another command could be introduced for this.  I don't
expect that there would be such a need due to paper usually being produced
in a few standard sizes.

I'm not too sure what your use case is for this but perhaps the HTML output
would be more appropriate for this?

Display of mathematical expressions may be difficult with HTML, but it is
supposed to be possible.

Writing manuals is the main purpose of Texinfo.  It is not a general
typesetting or formatting system for the display of arbitrary information.
