So you are admitting that not ALL DOS applications will run today,
only "Well-behaved MS-DOS applications"?


Yes. Poorly written applications may stop running even from one update of an
operating system to the next. In the case of MS-DOS, many such applications
bypassed the OS to access the BIOS or the hardware directly, and applications
like those often stopped running long ago (sometimes even under MS-DOS).
