Potential bug in .NET SDK 6.0.400-preview.22351.4 compiler

[AraHaan]

Version Used: Locally: 6.0.400-preview.22301.10, On Github Actions: 6.0.400-preview.22351.4

Steps to Reproduce:

This small codebase should be enough to reproduce it: https://github.com/AraHaan/remora-extensions.

(I would try sharplab but I fear it might not be as up to date with the version of the compiler that the CI automatically installs using the .NET Install scripts)

Expected Behavior:
For https://github.com/AraHaan/remora-extensions/blob/main/AraHaan.Remora.Extensions/Hosting/Host.cs#L34 to compile just fine in CI just like it does locally on my computer.

Actual Behavior:
Compiler error triggers on this line in CI, however locally it compiles just fine: https://github.com/AraHaan/remora-extensions/blob/main/AraHaan.Remora.Extensions/Hosting/Host.cs#L34
The interface used in that code: https://github.com/AraHaan/remora-extensions/blob/main/AraHaan.Remora.Extensions/Hosting/IBotServiceConfigurator.cs

More Details:

/home/runner/work/remora-extensions/remora-extensions/AraHaan.Remora.Extensions/Hosting/Host.cs(34,28): error CS8920: The interface 'IBotServiceConfigurator' cannot be used as type argument. Static member 'IBotServiceConfigurator.BeforeConfigure(Assembly)' does not have a most specific implementation in the interface. [/home/runner/work/remora-extensions/remora-extensions/AraHaan.Remora.Extensions/AraHaan.Remora.Extensions.csproj]

I think this was intentional. See dotnet/csharplang#5955.
It should be documented as a breaking change if it's not already.

Closing as by design.
