It's not too bad, assuming the first argument just needs ordinary
default completions.

compdef -e '((CURRENT>2)) && {
words[1,2]=(kubectl); (( CURRENT-- )); service=kubectl;
} || words[1]=:; _normal' kubectldc

If there is already a completion function for the DC argument, you can
replace "words[1]=:" with an assignment to service to select that
completion.
