(received privately, answering publically)

any AS owner who wants to localize these updates can do so by simply
anycasting the 192.175.48/24 netblock and serving dns on .1,=20
.6, and .42.

Will it be a _bad_ thing if I just null-route those addresses in a
controlled/documented/restorable manner in the ASes and other sub-AS
networks that I administer?

not at all.

Will it break anything valuable to you or to end-users inside those ASes?

nope.

Is there is a certain reason I should run a real DNS server on 1, 6 and
42 (besides, of course, collecting statistics and chasing ab|users) ?

nope.

Is there a centralised place with information on the blackhole-X anycast
addresses and AS112 or a document with the proposal and implementation
besides www.root-servers.org ?

um, nope.  if you think it should say more than it does, let us know and
we'll plump it up.
