Maybe there should be more discussion about these types of cookies (most 
aren't even aware of them or their capabilities), how to PREVENT them - 
to extent possible & how to clean them up.  They are NOT easy to get rid 
of if they've been placed in many / most of the known locations they can 

Also, FAQ on them.  I read the design links for New Identity &  the bug 
links, but I didn't see how that handles ALL the known locations where 
evercookies can be placed.
Another view is, "An ounce of prevention is worth a pound of cure."  I 
think educating users how to avoid them, to the extent possible, would 
be good.  They're often easier to avoid than eradicate.

I can't vouch for these clean up utilities effectiveness on 
evercookies.  I use them, but haven't tested much on evercookies.
BleachBit claims it will clean evercookies (recent versions).
CCleaner (some forum moderators) claim it will clean them, but I 
couldn't squeeze out of anyone at Piriform, that CCleaner officially 
claims to handle evercookies (meaning, all known "hiding places.")
