Additions and changes will assist developers installing / downloading releases / assist management of libraries for different platforms. Allow ProjectGenerator and alternatives to download addons / update cleanly.

Great.
I'll just share one idea that is different from that. in my ofWorks efforts I was trying to have an internal of file format for projects so it is backend agnostic (no make syntax eternally embedded on projects).
And the idea that projects and addons are the same thing, with the same kinds of properties that can be summed up. the only difference is a project has a main.

And having one source of truth to separate ofGen project settings totally from backends, making them swappable over time.
I'm just sharing as an idea as I'm focusing less on OF nowadays
