You will need it. Grep.geek doesn't crawl through New Nation's tld (.ti (tibet), .uu (uyghur), .te (tamil eelam), .ku (kurdish), .ko ('internal use'), .rm ('private use') so if there even is an actual domain associated with these tlds (there is a shockingly very good chance that there isn't) I haven't found them.
