"DOS support" is tricky inasmuch as a lot software from that era - especially larger and more complex packages - interacted with hardware directly. In a sense, they weren't really DOS applications so much as they were bare-metal PC applications which were booted from DOS. It'd be difficult for WINE to support those, and other projects like DOSbox / 86box / etc do a better job of it.
