Loggers are just façade objects on Handlers, which is an interface. It’s really designed to be a minimum necessary package to allow interop (via handlers) and a baseline of standalone usability (via loggers). The stdlib only provides a text and a json handler, not even a no-op handler which I think is sorely neededor a multi handler which I think would make a lot of sense. But nothing precludes you publishing a messagetemplates handler, or whatever else you may want.
