Noting that for Blazor, client-side request streams is on #33693, which is scheduled for review in a couple of weeks.

@guardrex That's great, but I don't think that was added in RC2, correct? Looks like it was added late last year and we just missed it in the early .NET 9 preview release notes.

Yes, it wasn't on whatever list I started with for 9.0. I discovered and added it as soon as I became aware. I'm ready to move forward with that PR after the assigned engineer comes in to assist with the two known open questions.
