Recommendations for splitting a large API into multiple handlers?

[johnrutherford]

If you have a large API, implementing all endpoints in single large Handler will be difficult to maintain. The GitHub API is an extreme example.

Typically you would want to split up your implementation by version, resource, etc. How can you do this with ogen? It looks like contiamo/openapi-generator-go uses x-handler-group to group operations into separate handlers.
