Shopify moving to StyleX is a wash in almost every metric. Wash = not enough gained in one vertical to offset the loss in another While it is more deterministic, our agents arent struggling with our CSS Modules. Over 10% of our CSS can't exist in StyleX too, and we'd lose our design system strategy that helps keep specific aspects private and others public. We also have a lot of adaptive CSS props and props that use dry switching to enable robust and terse adaptive props that StyleX can't express. We also have a design system in web components that could technically adopt it, but practically it's not a good match. Was a fun investigation! Same with investigating moving entirely to an OOCSS strategy last year, was fun but we've got enough modern CSS, tight strategies and gzip is amazing; the juice isn't worth the squeeze.
