StephenProposition doesn't work with sse data when input contains also other data than json. It's not a problem for StreamJsonParser. StreamJsonParser tolerate garbage input like fiddf { "object": { "name": "hello" } } fdsfgf24rf >> { "object": { "name": "hello" } }

dotnet run -C Release /optimize --framework net8.0

StephenProposition requires also adding new dependecies to SK: https://www.nuget.org/packages/System.IO.Pipelines/
