Ideally I would like to have labels/attributes that are attached to mappings. (This is captured here: https://github.com/grafana/pyroscope/issues/4262)

This would allow us to store any information relating to mappings in the correct place. This is very aligned to what OTLP will have: https://github.com/open-telemetry/opentelemetry-proto/blob/c0a98a1847d3124ac5f9ecd02d0e2d2732bbb590/opentelemetry/proto/profiles/v1development/profiles.proto#L439-L440

@korniltsev May I work on this ?

I agree with Christian its better to wait until otel style mapping attributes are supported
