Trying (more in hope than expectation) to run an ancient DOS program under Wine, I get this failure:
err:int21:DOS3Call int21: unknown/not implemented parameters: int21: AX 0f9f, BX 005c, CX 0000, DX 005c, SI 008e, DI 005c, DS 107f, ES 109f
Sure enough, DOS3Call() has a series of functions, including 0fh, which are unimplemented.
Is there any reason why these functions should not be implemented? The win31 sdk doesn't mention any restrictions on which INT21 functions can be used, neither does Schulman.

Not really. But if you want a DOS emulator, use dosemu. Spent more effort getting Windows programs to run in WINE ;)
