The reason I think it would be useful is that I see
novice programmers frequently make mistakes.  Their
general go-to solution rather than manual pages is
Google and Stack Overflow, and there they tend to pick
up wrong use cases or unbaked solutions.

For 'sizeof', there is no good reference (other than
the C standard, I suppose) that allows them to easily
look up what it does or how to use it.

Having a manual page would, I think, help people.

What would be the right format or medium?

I mean, we ship e.g., cdefs(3), types(3), offsetof(3),
and c(7), which strike me as similar.
