Yes, it will partition the 'net.  When (seriously) will a v6-only
root-server suite happen (by turning off the remaining v4 roots) ?  Not
for a long time, probably a few years after the release of RFC7654 - 'IPv4
and Why are we still bothering with it?' [1].

( Randy, I get the point.  I also understand that a v6-only root won't
  happen for decades, and may not happen if people (then) really-really
  want to keep IPv4 around. )

In that it can only reach other v6-stack'd machines?  Yes.  To avoid a
partitioning of the 'net, some sort of v4<->v6 translator(s) will be
needed for a very long time, until the last v4-specific stack goes away,
or gets otherwise shot.

By the same token, if you enable nameservers on v6 *without* having the
same data available via v4, you have effectively partitioned your part of
the DNS tree.  This includes doing such stupid things as having divergent
zone data depending on whether your v4 nameserver(s) is hit, or your v6
nameserver(s) is hit.
