Great to see so many new features in Rails. Tbh, one of the reasons I use it for certain backend projects is how simple to do complex things.

Managing files and image variants is a pain when developing a site. Rails make it easy and even adds more features around.

However, I still think the UI layer is too coupled to the backend. Webpacker was a try, but I understand why it's deprecated. I would go on supporting common frameworks, even if it's just a template to organize the code.
