Sorry to hear about your experience.
We’d love to hear more specifics if you’d care to share them?
Regarding “bloat on the frontend”:
– Performance is very much a real concern for us and we are always looking for ways to make things more performant. Do you have any specific concerns around the bloat you are seeing?
Regarding “it is not extendible”:
While we definitely know there isn’t the same extendibility in the blocks as there were for shortcodes and some other functionality, I would disagree it isn’t extendible at all. We’ve been especially focused on the Cart and Checkout blocks for the past year or so and extendibility has been a high priority there with a number of different ways to extend the Cart and Checkout blocks already in place (and implemented by payment methods, Subscriptions, and other extensions). However, we’re definitely not done here yet.
Regarding “It’s absolutely unusable”:
I understand it may not be usable for your context and that’s largely one of the reasons this remains a feature plugin for now so folks that don’t find value from the functionality can disable the plugin. We are very grateful for the many people who have used the plugin and are providing valuable feedback that help us identify areas to improve so that we are building something useful for merchants and stores. That’s definitely why we release a lot of the work we’re doing through this feature plugin so that we can get that early feedback.
