Look at pages 2 and 3 of the Fender licensing agreement, found under the neck options menu.

I know many people loathe legalese, but I've always gotten a kick out of it so I actually read licenses, contracts, agreements, etc. This agreement is interesting in that a cursory examination of it shows the trademark registrations for Fender's headstock shapes expired nearly 11 years ago. Perhaps this is why everybody + dog makes Fender necks now, but nobody takes any trouble to boast about compliance to any standard, and often they aren't exactly perfect fits. They just use the headstock shape and let everybody assume they're getting what it appears they're getting. In other words, "buyer beware".
I wonder if Warmoth needs to adhere to this agreement any more? It would seem they could still make the same necks without it, and they could do with them what they will. For instance, build guitars.
Not that they'd want to. I gotta think that's a brutal business, what with it being so subject to emotional decisions on the customer's part. At least with parts, you have some objective criteria to base your performance on so you can defend what you've done.
