First, no problem with being blunt; it facilitates communication. :-)
That said, we're not keeping the files for particularly long, so
"archival" isn't an issue for us.
It's merely that the files are extremely compressible (compressed size
is about 12% the original), but for various reasons outside the control
of those of us who run the machines, we need to keep some number of the
most recent of them uncompressed.

And on the other hand, to find the log for 3 days ago, you need to have
a better idea of the current date than I generally do unless I check
(either my watch or `date`). :-} So there are trade-offs. :-}
Then again, I'm rather in the habit of using "ls -ltr ...." when I'm
interested in the more recent of a set of files.

Well, I certainly wouldn't object to the existence of such a feature,
whether or not I'd use it myself. :-)
