That may be so, but a lot of libraries use a logger that isn't zap and isn't injectable, or the library doesn't expose a way to inject a logger even if the logger itself supports it. Plus, if you have 3 dependencies, you'll end up with 4 different logging libraries you need to worry about. In the end, you end up having a mess around logging unless you only rely on your own code and don't use libraries.

(Should have phrased the parent better.)
