Hi, sorry for not responding sooner, didn't realize this post existed.
Traceway is fully OTel compliant.
Go: The original version started with Go SDKs. I've since moved to using Go OTel. I haven't updated those docs yet because the Go SDKs still work and are used in the wild, but they're on the deprecation track. Thanks for pointing it out.
Symfony: There were no good one-line OTel integrations out there for Symfony, so we wrote one. It is not a custom SDK, it's an OTel configurator. You can use it with any backend, not just Traceway. We're firm believers in contributing back to the OpenTelemetry community.
Frontend / mobile: This is more complicated. The current frontend and mobile OTel spec does not allow session replays to be sent, so for those platforms we still keep SDKs with a custom protocol alongside OTel. As soon as the spec matures I'm hoping to move it fully to OTel.
