For a non-list option, I think it is very uncommon for a second occurrence of an option to override partial effects done by the first occurrence. Actually, I cannot think of an example off my head.

ELF linkers have an example of `-z defs`, `-z undefs`, `--allow-shlib-undefined`, `--unresolved-symbols` where `--unresolved-symbols` overrides both `diagRegular/diagShlib` while other options may override one of diagRegular/diagShlib.

That said, if this `/debug:` is useful, I think it is fine to be a special case...
