@josepedropereira @pellared should this PR be closed? What was the resolution of [this](https://github.com/open-telemetry/opentelemetry-go-contrib/pull/5431#pullrequestreview-2024891968)?

This seems duplicative of [`WithHost`](https://pkg.go.dev/go.opentelemetry.io/otel/[email protected]/resource#WithHost). Why not update that option?

Taking a look at the host semantic conventions, it looks like they are all experimental (even `host.name` :grimacing:). I think in the long term we want to make the `WithHost`...

@pyohannes can this be closed? We plan to move this into [this](https://github.com/open-telemetry/opentelemetry-go/blob/6d45f283c7abf2ee5284c769f9ae7109096d3564/sdk/resource/host_id.go) (behind the experimental envar), right?

Kick CI.

Client semconv template work is still blocked: https://github.com/open-telemetry/opentelemetry-go-contrib/pull/5773

We still need resolution for #6261 and #6262 to have a complete reference implementation to templatize.
