Per long-established consensus on [[m:Wiktionary/logo]], reflected since ages on the main page, the default Wiktionary logo should be [[File:Wiktionary-logo.svg]], not the English-only en.wikt version.
This won't affect the 69 Wiktionaries which have defined a logo (local or on Commons) nor the 28 closed Wiktionaries (which are addressed elsewhere), but only the language versions which have not yet localised/chosen the logo.
