100% Agree that loading schematics will be tedious and annoying to do. There is 0 reason that we shouldn't be able to automate a factory, that's what we enjoy. Now, 1 person should not be able to support the needs of a build anything factory which can easily be done through a power system where the larger factories need exponentially more power(and whatever resource is consumed to create the power).
In addition, being able to transfer Items across cores would be fantastic and would actually allow for more people to work together. I do my portion and transfer it over to you. so we can have more people involved in a multi core large factory, where each core is much smaller and thus consuming less power to run for example.
Etc, you get the idea. there are much better solutions.
With their current solutions, we'll just raise prices of items so we can buy schematics and will still have a large factory ran by 1 or 2 people. this schematic change didn't do anything to bring fun cooperative gameplay other then maybe posting in an org, hey we need 10 ppl constantly making these schematics, and another 10 making these etc. and we just buy them off of them.
