kubectl safe should use the same autocompletion as kubectl

For ZSH you can do the following

alias ks="kubectl safe"
functions[_kubectl-og]=$functions[_kubectl]

_kubectl() {
    words[$words[(i)safe]]=()
    _kubectl-og "$words[*]"
}

# this can be improved and narrowed down 
zstyle ':completion:*' completer _complete _ignored _files

You can now add the below anywhere on your path. Ensure it is executable.

#!/usr/bin/env bash

# If we are completing a flag, use Cobra's builtin completion system.
# To know if we are completing a flag we need the last argument starts with a `-` and does not contain an `=`
args=("$@")
lastArg=${args[((${#args[@]}-1))]}
if [[ "$lastArg" == -* ]]; then
   if [[ "$lastArg" != *=* ]]; then
      kubectl safe __complete "$@"
   fi
else
   kubectl __complete "$@"
fi
