It used to be that stuff like resizing and moving images didn't work very well. But it looks like this is much better now. Some examples:

I would still want to be able to read the files into a bitmap image editor.

Let me repeat what I wrote a while ago: I'm ok with having SVG or some other vector format as the highest quality alternative, but there are so many pitfalls with vector formats, such as the fact that you can't hack together your own viewer because those viewers are too complex, unbounded file size regardless of image size, possible ambiguities when displaying in different viewers / sizes, ability to use excessively small text and other elements, etc. So I think for every image there should be a relatively low resolution (think ~ 640 pixels wide) version, which would be the authoritative version of the image. And RFCs should be "fully functional" even when their images are removed.

Both of these are commonly used in equations, would be interesting to say the least if they can't be referenced in text. Although I guess real mathematicians let the equations speak for themselves, the way real programmers let the code speak for itself. But allowing greek and italics in the text would make it very hard to read RFCs on traditional text terminals and/or converted to the current "legacy" format.
