draft-itojun-v6ops-v4mapped-harmful says:

o IPv6 nodes SHOULD NOT generate packets that contain IPv4-mapped
  addresses in any field.  (As a particular exception, it MAY be
  acceptable for fields referring to third-party nodes to contain
  IPv4-mapped addresses.  Implementors must ensure that, where this is
  allowed, it is done with great care.)

I guess, our situation perfectly falls in this.. There is no harm in sending the v4 mapped service addresses.. For example, We store IPv6 addresses, IPv4 addresses and IPv4 mapped IPv6 addresses of DNS in /etc/resolv.conf.. The underlying stack can take care of this and make sure that IPv4 packet is sent if the destination is IPV4 mapped IPv6 address..
