This fails to discuss the reason that TTL restriction was there in the
first place, as well as any security implications of the change.

Please see
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-6520
https://www.kb.cert.org/vuls/id/550620
and more.  This is a well known can of worms.

As said before: You should disuss such issues with your proposed
patches.  Not doing so gives the impression that you either

 a) don't understand the implications, or
 b) don't care about security

I hope neither is true.  Please reassure me by fixing this up.
