What is your stance on the future of runtime if this is deleted?

Right know I see depinject module config and runtime still exist, and only the example on how to wire that app is deleted. Would you consider runtime legacy or deprecated then?

This is just a draft to explore some new ways to wire up an application. We have been hacking on a few approaches so nothing here is final.

TBD on whether we remove runtime, but in the future I would like us to have only one way to wire your application.

Right, I am not commenting on the rest indeed, due the the big DRAFT in the PR title :D
but this direction looks very much like the deprecation of runtime (and prob depinject then).

Personally as the original author of depinject and runtime, I feel that it's unfortunate that we didn't either 1) fully migrate to depinject or 2) find a solution that was simpler and satisfactory for everyone. Dependency injection wouldn't have been my first choice for how to solve this because it introduces a level of non-linear magic, but given the complexity of initialization dependencies it was seen as the least bad approach. There were quite a number of working group calls that explored different options and ended up with the depinject approach. I don't know the full context of this new approach, but whatever it is, I suggest we carefully the consider prior work, why it is the way it is and its pros/cons.
