One thing to keep in mind, the main reason for Topcoat to exist is that many organizations are already using Rust for infrastructure-level or performance sensitive reasons and often just want to build a web app using the programming language they already use.

I'm not sure that projects like Topcoat and something like their ORM is a great direction for the project, and worry that they will possibly gain outsized adoption in the community based on name recognition rather than merit.

Rust in general

Unfortunately, you end up bound to Python’s poor performance and poor typing stories, which Rust solves in spades.
