Can you document how we know this doesn't reintroduce the problems we had with constructor injection before? #40521

@SteveSandersonMS I suspect is dotnet/runtime@a48e73a

It's essentially using new APIs.

I haven't done size testing myself, but given we are early in the release, I think we can make this go in, and observe if we find any regression in our regular runs. Are you ok with that?

It's less for us to keep track of if you just do a one-off manual publish locally to see the impact on final sizes, otherwise if some regression appears two weeks from now, we have to go through a whole detective process to trace it back to the cause.

I did measure the change for the Blazor hosted app in release configuration between main and this branch and the size is the same.
