This is a very bad idea for two reasons:
1. The IPv6 spec says that you MUST implement it, then having
something else say you MUST NOT actually use it is just bad standards
making
2. Maybe someone has a legitimate use for this, they should be able
to do so if they want
This whole issue is blown WAY out of proportion: the BSD guys should
not forward when forwarding is disabled, the router guys should
disable source routing by default (for IPv4, too, please). Problem
solved, bring on the next one.
If, at some later date, it turns out nobody uses this feature, rip it
out of the next iteration of the IPv6 spec. But please, let's not
overreact. Compared to what we had to go through with directed
broadcast amplification (smurf attack), this isn't much of an issue
at all, even if you ignore that IPv6 uptake isn't above 0 in a
statistically significant way yet.
