I’m a developer too, but the developer experience doesn’t matter to users. As a user of the app, it’s fast enough, cleanly designed, seems to be reasonably private and secure, and I haven’t hit any website with it where I’ve had to download chrome to view it or something.

You're a developer but you can't connect the dots between "features being hard to build and the inconsistencies between other browsers vs Safari" to how that might effect the user?
