As will any alternate API for detecting implementation.

The fact that it isn't reliable today isn't proof that it is a bad API (hence, Doug's "reductio ad absurdum" comment).

Incorrect reporting by hasFeature() by an implementation is simply a bug on the implementation's part.

Unfortunately, any alternative to hasFeature will likely suffer from implementation bugs or incomplete implementation like the examples you gave. Unless you have a counter proposal, I believe the only solution which will be reliable on the web *today* is to create and dispatch a test event yourself.
