getVersion() returns memcached version, not couchbase version

For whatever reason, when doing getVersion() on the php ext the showed version is not the couchbase one. I assume its the memcached one, but I think this will only confuse people.

Is it possible to change this to the corresponding couchbase version?

array(2) {
  '192.168.56.101:11210' =>
  string(18) "1.4.4_600_g7ea975a"
  '192.168.56.102:11210' =>
  string(18) "1.4.4_600_g7ea975a"
}
