Remote Write 2.0

No

Describe the solution you'd like
I'd like that Cortex support Prometheus Remote Write 2.0. This feature will be enabled by default starting with prometheus 2.54.0.

As such, I would like that Cortex users get access to this feature as well.

Additional context
prometheus/prometheus#14395
prometheus/prometheus#14498

FYI otel collector contrib has lfx mentorship project starting in September to add support in the remote write exporter for remote write 2.0. Tracking issue: open-telemetry/opentelemetry-collector-contrib#33661.

Is there anyone working on this yet? If not I'd be happy to commit some time to it.
