just a suggestion...
( another feather in the pillow fight , as it were!)

Separate "Panel boards' could be fabricated by various parties with
expertise and allegiances to the various formats.

These would be configured to conform to the size, shape and quality

to the main board by (perhaps) individual wires , point to point, or
perhaps, a ribbon cable with an AMP(-type) header

myself***) (but then i started with heathkits and TUBES!!!!) but i
thought i'd suggest it to see if this functions as a compromise .
