Hello George, thanks for your comment. Its nice to know my speculations have some link to what reality of GP team workflow is, especially since we all want it to be like that. :)
Regarding hobbyists taking more and more interests towards GP. That is the impression I got from FB group too. The way I understand this is the fact that SEO is now taking performance and accessibility as important factors in ranking. I think this fact is really in GP favour in terms of popularity.
You may have noticed I totally skipped even a mention of accessibility and performance in the text, and that part was intentional as these are goals of both Kadence and GeneratePress. There are differences in implementations worth discussing off-course, but the post is long even without this.
All in all, glad you enjoyed the writeup ... I'll try to keep it up. ;)
