Will this work too?

No.

The question follows: what the hell does it make this? What is special
in ipv4 that it needs to bind to its addresses? With IPV6_V6ONLY connections
to all the IPv4 addresses but listed ones will be refused. I guess it is
not _that_ thing which bind expects.

I'm not sure I understand what you mean.  Note that the last line is 
_tcp6_:

tcp6       0      0  *.53                   *.*                    LISTEN

So, I belive using IPV6_V6ONLY it should indeed work.

(The reasoning in Bind is that you can bind to addresses _only_ in IPv4 
but you don't have to.  It's done in these cases.  For IPv6, it's 
all-or-nothing.)
