@nbish11 Thank you for putting that together! Some notes:

1. It would be good to see the class and method names of the factories in question; the parameters too, if there's room.
2. The research document is not the place for recommendations, only for clarifications on what the research itself indicates.

Once that's done, we can better consider the need (if any) for a separate "create from globals" method/interface.

I will update the research document with the actual references to the names and params.

I put it all in the research document because I think it should be extremely clear as to why a createFromGlobals() method exists, why it was chosen as a separate method on a separate class, and why it goes against what the majority of projects have done.

@pmjones Let me know if anything else is missing.

Thanks for the CI and Cake links, I had been working with local downloaded copies, that helps a lot.

I agree, but the place for it is in the README under Q&A. The research itself should "document findings" not "present recommendations."

Thinking about this some more: in the interest of moving this forward, I'll take it as it is, and then move the text around to the right places. Next will be adjustment of the factory class to match the research more closely.
