I guess this is possible with the proposal, but I'd like to see structured logging in the runtime and in a way that is compatible with existing services, so that all libraries use the same logging infrastructure and such a way that it can be redirected easily without rewriting any logging calls.
E.g. when building a service on AppEngine you log to a buffer of 1+GB for all your servers implemented in various languages and can do structured searching by type: (debug, info, warning, error, critical), time:real representing seconds since epoch, and message: string. However, since system level "debug" is higher level than language level "debug" there should be several levels below "debug" used in libraries and frameworks that is kept in-memory only to avoid spamming the global application/system level debug-logging.
Having a flexible language level logging mechanism is good, but making sure it fits into existing logging-frameworks (that cannot be modified) is more important and what it should be evaluated against.
