Well, I did a quick test, just being hopeful. Unfortunately, all ship designs use MCs, including transports, colony ships, etc.

Hopefully, this can be patched in the DesignCreation file. Maybe a Master Computer line with choices of "Prefer," "Allow," and "Disallow" or something like that. Then the AI could use it when available, use it as needed but also discontinue it/supplement it with B/LS/CQ when necessary, or simply not use it according to the design.
