Do you have any real examples of significant recursive servers doing

nscd in GNU libc has issues related to cache expiry.  I'm not sure if
it is general brokenness, or some TTL-related issue.  It's use is not
terribly widespread, and it's a host-specific cache only, but there's
a certain installation base.

Thanks Florian. So this looks like a code "feature", not stupid behavior by deployers. I'll keep a note when we fingerprint misbehaving systems in the future.
