"Implementing stateful DHCPv6 would break planned use cases such as IPv6 =
tethering"
"And it's not possible to enable tethering"
"tethering cannot be made to work well"
"what do you expect Android to do if given only one IPv6 address and the =
user turns on tethering"
'Saying "tethering is not available" is not going to fly'
Yes, while you have mentioned a few other things, based on your postings =
on the issue thread tethering seems to be one of your hot topics.

As opposed to not supporting DHCPv6 operation forcing users to adopt =
phones based on operating systems other than android?

Thank you very much for being the guy in charge of determining what my =
problems are.
As I already mentioned in the issue thread, one of our motivations for =
moving forward with IPv6 deployment is that some grants our faculty want =
to apply for require native IPv6 communication. So an android device =
that is incapable of connecting to our IPv6 network due to deficiencies =
in its implementation of IPv6 standards will not be usable for that =
grant work. But I will be sure to tell the faculty that the android =
developer responsible for that breakage assures them it is not a =
problem. After which I will encourage them to switch to another platform =
which provides for its users' needs rather than its developers' =
crusades.
