I'm having a difficulty seeing the point.  A similar situation happens if 
the user has manually configured a few nameservers in /etc/resolv.conf and 
then runs either DHCPv4 / DHCPv6.

Is it IETF's business to specify whether or not (and if so, how) the
entries should be overwritten, prepended/appended, etc. ?  Is this done
now with DHCPv4?

I'm not so sure, but something like "DNS servers configured through this
option should take precedence if some existed beforehand" would be
acceptable to me Note *no* RFC2119 upper-case keywords.
