Well that's funny you mentioned it because one of my projects was a service that let users temporarily install binary info logs collectors triggered by predicates, remotely, which at least I thought was a better model than ssh into the host or, for the advanced caveman, pdsh into many hosts. I don't really see a reason why I can't do that for gRPC, either ...

But, anyway, remote command and control of observability really is a thing in the industry, not just at one company.
