Go is behind several of the languages in OTel right now. Just a consequence of a very difficult implementation and its load-bearing nature as being the language (and library) of choice for CNCF infrastructure. If you use Java or .NET, for example, it's quite fleshed out.
One would hope that there will not _be_ an Open Telemetry logging library for Go. Unlike last time there was a thread about this, there is now a standard - `slog` in the stdlib.
