The only thing I'd say we should do differently here is to change this metric:

integrations-core/datadog_checks_base/datadog_checks/base/checks/openmetrics/v2/metrics.py

Line 31 in 642b2f9

'process_start_time_seconds': 'process.start_time.seconds',

We should make it an elapsed time metric. I can do that. But then we'd have to make a release and bump the min base package in this check. The easier way maybe to overwrite the metric in your metric list.
