I don't recall off the top of my head some non-template innards
actually might require @safe, but apart from that, why not just
leave the job to template attribute inference entirely? If
somebody wants to log a type with a @system toString in
non-@safe code, why not just let them?

In my opinion inference is better choice for small building
blocks (like algorithms). For complete system like logging API
forcing @safe makes more sense as whatever its internals are,
exposed API should never be @system
