Does it mean if we merge this update our users should also upgrade their prometheus client too? If there exist any other metrics systems in their project, how can it work?

Users should replace dependencies instead of upgrade them ,I don't think it will affect the work of other metrics. of course, this requires your evaluation
new dependencies (prometheus-metrics-exporter-pushgateway、prometheus-metrics-core、micrometer-registry-prometheus)
