It's what's documented.  There are several categories of
options, and what you pass changes *only* the category
of that parameter.  The categories are what they have
always been:  signals, combination/bugs, and drive types
for nSRST and nTRST

So for example you can say how TRST is driven without
having to say how SRST is driven and whether the board
has bugs in that area.

Yes, that's a problem.  Not a new one of course.

That makes it impossible to combine constraints that come
from different spots, so I don't like that notion.

Is there some problem the current scheme has?
