if the purpose to disable compression is for debugging, then your
suggestion to "be brave and not compress the pdf at all" is the best

the rest of the need to prevent compression seems to be for specific
streams such as metadata, where it is enough to use an option in the
\pdfobj, instead of making a more complex approach with whatsit nodes.
