Sure, it may not be feasible, but it is an alternative to manually
having to disable one's entire IPv6 connectivity and then re-enable
it later!
If you notice a problem with Y! (or whoever) then you may have
encountered a new netblock and at that time can just add another
prohibited route for it. There won't be many in total and it won't
matter if you pick a whole /32 or /29. v6 allocations are
purposefully intended to be huge so that organisations won't go back
for more and need extra routes in the global routing table.
Cheers,
Andy
