Also note that you can rewrite it as:

SELECT ?item ?host (bound(?host) as ?p1)
{
	?item wdt:P31 wd:Q3917681
	OPTIONAL {?item wdt:P17 ?host }
}

and that works.TASK DETAILhttps://phabricator.wikimedia.org/T145868EMAIL PREFERENCEShttps://phabricator.wikimedia.org/settings/panel/emailpreferences/To: SmalyshevCc: Smalyshev, Aklapper, Esc3300, mschwarzer, Avner, debt, Gehel, D3r1ck01, Jonas, FloNight, Xmlizer, Izno, jkroll, Wikidata-bugs, Jdouglas, aude, Deskana, Manybubbles, Mbch331___
