Tracing limitations

emit's tracing model is intended to be simple, covering most key use-cases, but has some limitations compared to the OpenTelemetry model:

• No distinction between sampling and reporting; if a span exists, it's sampled.
• No span links.
• No span events.

Additionally, there is no guarantee of monotonicity; span extents are based on a start and end timestamp, so shifts in the underlying clock can produce misleading results.
