Gotcha. The difference is important, since a good log framework won't simply delegate, but will first check that the log level is enabled. This often matters, if there are any log statements in high-cardinality loops, since the memory pressure of creating all the strings adds up, but the trivial stack frames can often be optimized away / trivialized, depending on the language, runtime, etc. I used to be a big believer in doing manual log-enabled checks, but man, does that make the code noisy. I still do that when I want to log something non-trivial to compute, but that's the exception, not the rule.
