 We switched to the [w3c Baggage spec](https://www.w3.org/TR/baggage) though because it was easier to use, required less code on the SDK side, and had much more [liberal size limits](https://www.w3.org/TR/baggage/#limits) than the trace context spec.
 To make sure that we were not colliding with user defined keys as baggage is an open standard, we decided to prefix all sentry related keys with `sentry-` as a namespace.
 This allowed us to use baggage as an open standard while only having to worry about Sentry data.

-- Why must baggage be immutable before the second transaction has been started?
-- What are the consequences and impacts of the immutability of baggage on Dynamic Sampling UX?
-- Why can't we just make the decision for the whole trace in Relay after the trace is complete?
-- What are the differences between Dynamic Sampling on traces vs. transactions?
