Interesting.

I never use annotations in my own tools, I add first class abstractions for whatever database features I need and free form records to shuffle data. So there will be something called a Table, with Columns and Keys. It's not so much reinventing as bridging, an FFI doesn't reinvent the library it imports.

And yes, that means you can't modify the database from the bottom any more. But you're not losing any power, since any random programming language is more flexible and convenient.

Most databases come with some kind of built-in DD, I've used them in Firebird & Postgres to read primary- and foreign keys while I was still investigating the approach.

But it never really clicks for me, because the database is not the software, it's where the software stores its data. Tying application logic and presentation to the relational structure of the data just doesn't make any sense to me.
