TBH, I don't think the rotation configuration options need to cater for
stupid choices, and what you're describing sounds like a stupid choice.
Why wouldn't you configure, say, a finite set of daily- or hourly-named
files? Even just ping-ponging between two log files would be enough to
prevent the scenario where you lose the freshest log entries.
If you don't care about keeping even the latest entries, then you don't
need a log at all, much less rotation --- just pipe it to /dev/null.
