I think we could infer span context from request headers so each server integration doesn't need to change. Possibly even backfill during event processing although if that is necessary tracing is already broken |

Is there a reason why we just can do "new SpanContext"?
The ctor can set the values, since we are not measuring time, this can simplify the API.

For prosperity from a conversation in person: Mostly just so that the ctor will not attempt to auto generate. We can change this, that was just an early draft.

This is the most basic hack I could come up with that gets us into the direction
of correlating errors. It currently uses a made up
tracecontext but i thinkrealistically speaking we probably want to use attributes for this.
