LGTM as an implementation but I have a question about whether this is necessary as a feature. Are customers likely to actually do this?

[bidetofevil]

It's part of the OTel Span API and something iOS already supports. I don't know if customers will use it, but it's part of the API and it's relatively easy to implement (without needing anything on the server), so I just did it to reduce on area of potential differentiate between our implementation and the official Java OTel SDK's.
