The issue I usually have with these logging libraries is that they often don’t handle structured data well, which is something that’s commonly needed in a logging library.
For example, it’s fine for log entries to be a string when logging to console or a text file, but if you add a sink that logs to a database, service (Sentry, Loki, NewRelic, whatever), or JSON file, you’ll generally want some sort of structured data. At the minimum, you’d want the format string (e.g. "Unable to find {id}") and the variables (e.g. {"id":123}) to be stored separately, so that you can get aggregated counts for how often each error is being thrown regardless of the variables.

LogTape also supports structured logging. Structured values are kept in
LogRecord.properties. Please see how to use the JSON formatter.
