Of course, the ultimate expression of that idea is to use a 90 degree

Add a Z axis multilayer pin to cover multi path source to destination.

The normal (and nominal) routing is (or can be) to the adjacent

 Not applicable to all, but have used the small 10x10 x-y matrix
pin boards in the past to patch comms lines, eg: null modem
or pin to pin, or combination of such. Visually obvious which pin
goes to what as well. One of those glued between a pair of 25
pin D, in one example.

[My solution for EIA232-ish "conversions" is to build small
(2"x2") adapters that permanently hardwire a connector (of
a specific gender) on one end to another connector (of a
possibly different gender) on the other end.  Then, slap a
label on the assembly:  "Null Modem", "Null Terminal", "Male
Gender Swap", "Female Gender Swap", "APC UPS", "PLIP", etc.
The thinking being that if you have to sort out how to connect
X and Y *today*, you will likely want to connect them, again,
tomorrow.  So, make a specific adapter, document it, and be
done with it.  I only use my "patch board" to sort out how
to make that first adapter.]
Here, "visually obvious" is the problem.  I need a solution of
which someone who is blind, physically disabled, etc. can make
effective use.
You (likely) can GLANCE at a network switch and see if a
node is inactive (if you assume all would be active).
And, can see if there is a network cable plugged into
that port.
Close your eyes and do it.  Or, confine yourself to a wheelchair
that limits your reach or the ease with which you can "navigate"
a panel with hundreds of connections.
If you were told to swap the cables at connections X and Y,
would you be able to do it -- correctly?  (no peeking!)
How do you locate X and Y?  Hold onto the X cable while
fiddling for the Y?
