Funny, I replied in the "WP Engine Launches Genesis Pro Add-On for Customers, More Features in the Works " article back in May 2020. It took them a full year but I'm glad they finally followed my advice, to quote:

"If Genesis Pro was included with the Pro Plus All-Theme Package, it would have made it much more attractive to new customers and encouraged current customers to stick with Genesis."

Best of luck, guys. Glad you came around.
