Wouldn't it change in some cases?  Where you have schematic with signal nets
drawn to show flow of signal through a system?  And where your symbols for slot parts
do not go down to single sections?

In that case, nets drawn to not overlap and "appear" simple and streamlined might have to change
to crossing over some to allow for a decision made based on layout goals.

Yes, one could avoid that happening by strategy.

Strategy might not get executed all the way in real life.  I don't assume changing the pinnumber=
attribute on existing symbols is all that will ever be needed, even if it handles most cases.

I was suggesting tools to handle those cases.  Tools like special colored ratlines for the back annotated as built nets.
The ones that were not done strategically.
