Show me where I asked for a framework that magically turns Rust into Ruby. The person has created a list of (high-level!) features that they need. None of them are 'no borrow checker'.
It'd be cool to have an out of the box "90% of what a website needs" toolkit that means writing your 10% custom code/secret-sauce in a modern code security obsessed language. Even if it is opinionated and "batteries included" in ways that make some things annoying.
I have built many projects that start with a WordPress install, to piggyback it's CMS, user management, and admin backend. I then inevitably end up making a choice between writing the project in php, or jumping through hoops to use the WP features (like auth and user accounts) in some other language that's more appropriate to the task at hand.
