[Coco] Glenside IDE + Multi-Pak + HDB-DOS

I apologize if I seem pedantic, but we seem to be talking at right angles, Bill. I know how to jumper the Glenside IDE hardware. My question is specifically about Boisy's comment in the HDB-DOS source code from Toolshed which states:

"note that the Glenside IDE controller does NOT work with an MPI using this current version of HDB-DOS"

My question is:

Is the addressing conflict at $FF7F the *ONLY* reason behind that comment in the HDB-DOS source code?

I suppose I can also ask a related question: Why would a user without an MPI "probably want to use the 16-bit $FF7x driver"? Wouldn't the $FF5x configuration work in all cases?

My motivation for asking these pedantic questions is that I'm designing a compact Glenside-IDE-compatible CF card adapter with ROM to fit in the lovely SuperPak cases, and I want to fully understand any compatibility issues so I can maximize its utility to anybody who might be interested in it. I'm left wondering whether there's a real need for it to support the $FF7x base address at all. Eliminating an unnecessary configuration switch would very slightly decrease cost and complexity.
