In particular, I've heard that you have to use a better HIMEM if you want to use > 64 MB of RAM w/ DR-DOS (although still limited to 64 MB per process in /MULTI due to hardcoded limits).

Anyways, I didn't say it wasn't moot, just that it was fairly strange behavior. Maybe for best compatibility HX should try XMS 2.0 calls by default if the 3.0 ones fail.
