Description
Activity class is essential part of distributed tracing and log correlation, see: https://learn.microsoft.com/en-us/dotnet/core/diagnostics/distributed-tracing.
Activity class by default is created for each asp net request. It produces fields like TraceId and SpanId which helps to identify and correlate calls across multiple services (its automatically included by HttpClient as well) without writing any additional code.
So far emitting these fields was implemented few years ago in Serilog JsonFormatter, see: https://github.com/serilog/serilog/blob/dev/src/Serilog/Formatting/Json/JsonFormatter.cs#L74-L84 .
In my opinion - Http text formatters should also include these fields by default without a need to make custom overrides.
