It’s not just missing features/docs/bugs that are an issue. Lack of versioning means Shopify can break working apps without any warning or update – and with the QA as it seems to be, this is feels like a major deal breaker on using these components in production.
I think you can technically serve your own fixed version, but without versioning on Shopify’s end, it’s hard to know when things have updated/what has updated. I’m not sure what to do, honestly.
