[erlang-questions] Should we deprecate or modernize log_mf_h and rb?

[Richard Carlsson]

If anyone is interested (hello Martin and Siri!), we have slightly
modernized our rotating cleartext logger handler to keep it compatible with
recent OTP versions, and split it up into three separate modules, one as
api and handler-supervisor, and one for the formatting of messages.
Available here, as a diff on top of the old version if anyone still wants
that:
