If one of our customers want to kill their IPv6 connectivity, they certainly
can do so... as we're not sharing /64 between different customers (that
have the necessary permissions to change their IPv6 address) all they can
do is harm themselves.
So for *us*, this is a not overly serious problem and we haven't yet done
anything about it.
It could be a problem at exchange points if one of the colleagues fat-fingers
their address, but then, if they do it for IPv4, breakage will ensure just
as well - and so far we've not seen to many incidents of that...
