need low, and even very low, magnification to see most
DSO's, but that's not necessarily true, is it?

No, indeed it's not. For very small DSOs, you will often want to use
higher magnification.

Of course, you wouldn't want to use a 5mm on a galaxy.

I think there is no "of course" about it. I often want to use a 5 mm
on a galaxy in my 70 mm Ranger. That kind of an eyepiece would only give
me about 96x, typically yielding about a 1/2-degree true field of view,
and nicely framing many DSOs.
