No worries.

Something like that, yes. Though I would spell it
log_mgr.add_appender("app.*", some_appender)
or (if a singleton log_mgr)
get_log_mgr().add_appender("app.*", some_appender)

Yes, names are fine - I'd certainly use that approach in the default
manager. I still think the actual sink should be oblivious to this,
