Why not just:

component.queryMultiAdapter((bar,baz), IFoo, default=False)

Well, it seems that if I have:

class Foo(object):
    .    implements(IFoo)

context = Foo()
component.queryAdapter(foo, IFoo, default=None)
None

I assume it's the same with single adapters? As I said, I may well be doing something wrong, but that's what was happening to me (using Five, Zope 2.9.2). If it makes any difference, the interface in question (IFoo) was applied to the class Foo using <implements> in ZCML (legacy/backwards compatability issue).
