cache dump lists stale TTLs - intentional?

While backporting serve-stale to the 9.11 subscription branch I noticed that rndc dumpdb -cache has changed its output; records in the cache dump now show their total time to live, not just the time until they become stale.

The dump file does include a line that indicates what the stale TTL is set to. You can subtract that from the reported TTL and find out what the record's original TTL was in the auth server reply. So this may be fine, but it wasn't the behavior I was expecting and I wonder if it needs more condsideration.
