I've done this on a few older bikes but stopped for two reasons:

1. Many fork manufacturers will refuse to honor their warranty if you do this. Kestrel and Easton both say it will void their warranty.

2. If you ever sell the bike and have removed a "safety feature" it could cause problems if the new owner has an accident.

I found it three complete turns of the nut free most front wheels so I just count turns when I remove and replace the wheel and the qr adjustment goes back to it's proper tension.
