I prefer DROP/CLEAR ALL does everything, including the default graph. "ALL" implies that to me.
If I really want to leave the named graph, and CLEAR the others I can do that with:
DELETE WHERE { GRAPH ?g { ?x ?y ?z } }
Admittedly there's no DROP equivalent, for graphs that don't do empty graph culling, but that's well into corner cases AFAIC.
Otherwise, you could add a "GRAPH *" like syntax, meaning all named graphs, but I predict that users would confuse GRAPH * and ALL a lot.
