Turns out the agent ignores the root_span_tags for v0.7 anyway. This is useful to coalesce chunks with common data, allowing us to actually save us from doing redundant requests. As it was currently, the agentful trace sender always sent one trace per request, instead of merging them.
We also skip normalization and rely on the agent to do it, for sake of consistency with other tracers and reduce the potentially duplicated work across tracer and agent. We may change that back in future, but for now we've determined it to be the easiest way to work, also with respect to normalization-unaware testing.
