well, I have seen spams (buil, unsolicited) containing large attachments -
jpg, doc, pdf... While they are not common (you have described the
reason), but they are still annoying, and they are spam (many of them is
from stupid marketing companies or idiots who believe their activities are
something that most of people should know about).

So, there are reasons why we SA might scan them. Of course, SA can scan only
text parts, but luckily there are plugins that may convert between different
formats, e.g. FuzzyOCR who tries to read images and/or ExtractText that
tried to extract text from other formats to get scanned by SA.
