I am not implying that it should, but to answer your question, because limits on accepted forms of expression are not necessarily a good thing. Not necessarily a bad thing, either.
People already mentioned some pros (e.g. graphs and such help cross the inferential distance) and cons (e.g. images break the mental flow of some people).
Why shouldn’t it be?

It doesn’t feel like a limit to me, just something that very seldom occurs to me to do because I very seldom have any use for it.
(I sometimes link to images—maybe next time I’ll consider including them directly in the comment.)
