Why meter is in a seperate package?

[davendu]

To create a tracer and start a new span, one can use:

import "go.opentelemetry.io/otel"
//...
ctx, span := otel.Tracer("com.application/handler").Start(ctx, "current_call")

But to create a meter (with related counter), one should use:

import "go.opentelemetry.io/otel/metric/global"
//...
meter, err := global.Meter("com.application/handler").SyncInt64().Counter("call_count")
panic_if_err(err)

There seems exists some inconsistency. Why global.Meter is not placed in otel package? Is there any deep reason to do so?

The metrics API is not stable yet, it is not covered by our stability guarantees and may still change. The go.opentelemetry.io/otel package is stable.

Once the metric API is stabilized an alias will be added to go.opentelemetry.io/otel for that function.

Thanks for the info!
