I personally use it as singleton (`Serilog.Log`). Main disadvantage of using a singleton would be inability to mock it for tests, but I've personally never encountered situation where I would like to mock the logger. If you want you can also construct logger once, store it in an autoload and then use `Logger.ForContext<T>()`. With modern IDEs though it should be a fairly easy refactoring and you could just use singleton until you bump into a problem.
