Yes. And the current behavior seems intentional (it is documented): to print command line options as an uncategorized list, `-help-list` can be used (https://llvm.org/docs/CommandLine.html#grouping-options-into-categories).
FTR, LLD, llvm-objcopy and few other tools use a different approach based on `llvm::opt::OptTable` for parsing options and we have no strange categories there.

Seems if we want to change this for llvm-objdump we probably might want to reimplement it in the same way I guess.
