What are you trying to achieve?

I'm currently working on the micrometer->OTel bridge instrumentation in the javaagent. Micrometer offers the possibility to remove a meter from the MeterRegistry and stop emitting whatever metrics it used to collect. For example, suppose you use a database connection pool that's instrumented with metrics - when you close/destroy the whole pool you probably want to stop collecting any metrics associated to it (because it doesn't exist anymore). This is useful for both asynchronous instruments (since once they're registered there's no way to stop them) and synchronous instruments (you can just stop using them, but the metrics SDK will still send in the last recorded value).

Additional context.
