What kind of practical data?
FWIW,
<https://tools.ietf.org/id/draft-ietf-6man-deprecate-atomfrag-generation-00.txt>
seems to be good enough when it comes to reasons for deprecating them.
Besides, please check Section 5.2 of
<http://www.ietf.org/id/draft-gont-v6ops-ipv6-ehs-in-real-world-01.txt>
-- my "connection" to kernel.org was vulnerable to such attack.

<https://tools.ietf.org/id/draft-ietf-6man-deprecate-atomfrag-generation-00.txt>
was adopted by the 6man wg last November. While the I-D is not ready an
RFC, and there might be minor modifications, it seems that there's
agreement in not generating atomic fragments.
If you do want to have a sysctl for this, please make it default to "off".
Thanks!
