In particular comment 105 is illuminating. Android is apparently fully
on-board with mobile carriers' desire to break tethering, even going so
far as to implement a feature whose *sole purpose* is to break
thethering.

Yet, at the same time, you refuse to implement DHCPv6 on WiFi because it
*might*, as a *side effect*, break tethering. This does not strike me
as very consistent.

If Android had instead simply refused to establish a mobile data
connection to the mobile carriers that breaks tethering, then the
refusal to implement DHCPv6 would make much more sense.
