I wasn't intending to create a formal guideline, but one example I encountered
recently is ResourceRequest, which has String and KURL single-parameter
constructors without the explicit keyword.

The FrameLoader class has about 25 methods that accept a ResourceRequest
(e.g. various load methods), so all of these also accept a String and
KURL.  This makes it harder to know the right way these methods
should be getting called.  This also makes it harder to refactor.  Call
sites seem to use all three variations.  The class also has other load-like
methods that accept a String url, and others that accept a KURL url.
