Semantic convension for logged in username?

[stnor]

Hi,
Is there any thoughts on adding semantic conventions to collect end-user attributes (eg username, roles) to the spec?
I can't find anything at the moment?

Most commercial tools for looking at traces such as AppD, AWS X-Ray etc that I've used have at least username as a filter dimension in their ui.

These attributes are hidden in span-general.md: https://github.com/open-telemetry/opentelemetry-specification/blob/v1.3.0/specification/trace/semantic_conventions/span-general.md#general-identity-attributes
