We've seen this on economist.com (using modernizr) in the past, although I believe it doesn't do that any more.  I think a soft-promise type API could work better - supportsContext("...") -> false means we definitely won't return non-null for getContext("..."), but we're still allowed to return null for getContext("...") even after saying true to supportsContext("...")
