Create the section view the old way. Place a sketch line first, lock it down with relations, dimensions, or other lines as needed, then select this line and activate the section view command. It will use this sketch line. Hide any dimensions and move other sketch entities (if any) to a Layer that's turned off.

This is the old way, huh? :-)

I created a sketch in my model. I went back to my drawing.
select this line and activate the section view command. It will use this sketch line.
It does not. I can't even select the sketched line to place the cutting plane line. Actually, the sketch line lights up orange when I hover over it, but when I click, it doesn't actually use that line - when I zoom in, the point that was selected is not on it.
Oh, did you mean a sketched line in the drawing? That seems to work as directed... Wait, how can a sketched line in a drawing be fixed to the midpoint of an edge, when you can't do that in the model?!! OK, well this would solve my problem easily, except for that part about the other feature wiping out that midpoint relation when it is suppressed. How do you use global variables in drawing dimensions?
It turns out I can't add a coincident relation in a Drawing between a sketched line and the midpoint of a model edge. I apologize for that. I'm very surprised that I never noticed it before. However, if you already have a sketch line in your model just make your line in the Drawing co-linear with it. Or place a sketch point coincident with the midpoint of the edge (it should snap when placing it), then make the sketched line coincident with the sketch point. Later move the sketch point into a layer that's turned off.

OK, I'm good. There's still a lot of awkwardness, and having to fix drawing entities when things change, but it works.
