But when the Safari 14 GM release came around, I couldn't justify spending $100 per year just to get my extension on Safari. My goal is to test my product ideas. Chrome gives me plenty of installs to do that, and Safari's user base is too small on the desktop. Adding Safari also means that I have to manage another release system, deal with all of Apple's app store approval quirks, and support customers on a new platform. The added $100 / year just adds to the trouble.
I still think Safari supporting WebExtensions is a big win for the web platform. When I do scale and when Apple sorts out the new platform quirks, I think I will pay the $100 per year and all the added time and technical costs.
