On another note, would it be possible to pass the "dump_level" in the
diskdump header somehow -- while maintaining backwards
compatibility with compressed-diskdump files?  Perhaps in the
upper bits of the diskdump->header_version, or something
like that?

I think it would be useful to know exactly which types of pages
were excluded from a dumpfile when analyzing it.
