thoughts on using c#14 features in the project?

[SimonCropp]

eg extension members https://learn.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-14#extension-members

given the project already targets a preview of SDK 10, i assume people are using a preview of VS to work on the code base

however r# and rider previews are lagging behind support for c#14, so for those people it would still build, but intellisense would not work for those features and the IDEs would highlight those features as bad code.

the reason i ask is there are significant improvements that can be made to Polyfill (and consumers of Polyfill) by leveraging those features. so i was contemplating deploying a beta of Polyfill that targets c#14.

For extension members, I think it's fine as long as it's not used in public API (please let us know of the exact changes though). @nohwnd Thoughts?

Yup, should be fine.
