Use Zeitwerk

Zeitwerk is an efficient and thread-safe code loader for Ruby.

Given a conventional file structure, Zeitwerk is capable of loading your project's classes and modules on demand (autoloading) or upfront (eager loading). You don't need to write require calls for your own files; instead, you can streamline your programming by knowing that your classes and modules are available everywhere. This feature is efficient, thread-safe, and aligns with Ruby's semantics for constants.

Zeitwerk also supports code reloading, which can be useful during web application development. However, coordination is required to reload in a thread-safe manner. The documentation below explains how to achieve this.

I see this in the logs when code is reloaded

Maybe it something that can be addressed in Sinatra? sinatra/sinatra#1319
