dumping an image in pdf mode is rather difficult to get right. If in dvi mode an image is "stored" by a reference to an external file, then I am afraid the speed gain is not that much. There is for sure some comfort by having a dumped file reference in the format, but again that can be also achieved for pdf mode using some macros IMHO.
to me it looks like a rather useless option to include an image in a format, just as we don't embed type 1 fonts in the format either so let's not waste energy on it
My vote is also to disable \pdfrefximage and the likes in init mode.
depends a bit what 'the likes' is, i can imagine that one wants to measure the dimensions of a graphic or so and store them, but indeed the ref to an imag ecan be disabled
I had that in mind too, that's way I voted to disable \pdfrefximage instead of \pdfximage. The likes here are \pdfrefobj, \pdfrefxform and perhaps those that can cause pdftex to write anything to the output. fwiw, pdftex has support for reading image dimension that can be used in dvi mode (added as requested by ChoF, who uses pdftex mainly in dvi mode and use dvipdfmx to create pdf).
also, those who generate a format should know what they're doing/dealing with
