Describe the solution you'd like

PersistentComponentState's TryTakeFromJson method uses System.Text.Json's auto generated sources of JsonSerializerContext & JsonSerializable
I'd like to use something like what asp.net core web API has as followings:

services
            .AddControllers...
            .AddJsonOptions(options => options.JsonSerializerOptions.AddContext<MyAppJsonContext>());

So aspnet core web API uses MyAppJsonContext globally to improve its performance.
I'd like to use generated sources of System.Text.Json in client side to read transferred json state

Currently blazor uses JsonSerializerOptionsProvider which is internal and we can't call .AddContext() to make sure it has access to our source generator based context

I understand that you have a lot of work, but given its simplicity, it can greatly affect the startup time. Do we have an update on this? Will it reach dotnet 8?
