In fact, this cannot yet be picked up, until we remove TermSearchInteractorFactory from Wikibase Services, as getPrefetchingTermLookup, is used in that method on SingleEntitySourceServices.

And as for TermSearchInteractorFactory, it’s worth noting that WikibaseClient has a method

	/**
	 * XXX: This is not used by client itself, but is used by ArticlePlaceholder!
	 */
	public function newTermSearchInteractor( string $displayLanguageCode ): TermSearchInteractor {
		return self::getWikibaseServices()->getTermSearchInteractorFactory()
			->newInteractor( $displayLanguageCode );
	}

but ArticlePlaceholder hasn’t actually used this method since March 2020 (removed in rEARP3c9ae982ece3: Drop legacy database search integration code). So as far as I can tell, we can remove the WikibaseClient use of that service directly.

The WikibaseClient method is gone, so now the TermSearchInteractorFactory is only used in WikibaseRepo.
