Even though DOS 5.0 includes many features of QEMM, they didn't quite
get it all right.  For example:

If you want to load drivers high, you will load the DOS 5.0 expanded
memory manager.  Then Lotus and other protected mode programs won't run
because the memory manager won't have any expanded memory to allocate.
To give it expanded memory to manage, you must turn on EMS support.
If you turn on EMS support, the DOS 5.0 expanded memory manager will
put a 64K EMS page frame in your upper memory, severely reducing the
space to load drivers.

Mature DOS memory managers like QEMM can manage expanded memory (allowing
Lotus and other protected mode programs to run) without requiring the
placement of a 64K page frame, which protected mode Lotus doesn't need.

I'm sure Microsoft will get it right eventually.
