Hey. Just curious - if I were to follow the progress on the upgrade, or help push this forward, what would be the right PR to subscribe to?

I started working on it. But I suspend due to

• axum 0.7 removed the simple gracefully shutdown (see its example and the comment related to hyper-utils)
• tonic was not upgraded for hyper 1.0 (being able to support multiple version of hyper in the workspace introduce lot of complexity for just a transition period).

PS: the migration of tonic to hyper 1.0 and axum 0.7 could take time, I'll see if something could be done to not block upgrade to axum 0.7

PS: PR are welcomes, I'll push mine as draft.

IMHO, half fixed but I close the ticket as a version is available for axum-0.7
