this is a big miss in the mac lineup. Apple have weird reputation with it's mac pro users, they spent a lot of money on those systems and yet apple can't decide what to do with this small but important part of their users.
I still remember people crying for a new mac pro, only to get the trashcan mac back in the day, they where furious with the lose of expand-ability and upgradability of the system and then apple said ok we got it and gave the last gen mac pros (although not without hicups like the crazy expensive wheels and the monitor stand...) but at least it was what a mac pro was supposed to be.
Now what happened again and they changed course? Especially now with the mac studio that can cover the pro users who where happy with the compact trash can.
If the unified SoC system is not ready for this yet, just don't release it...
