Disable it if you want, I'm just offering an alternative for people who wouldn't bother taking that precaution because it's inconvenient. You're not going to convince everyone to take the full measure, and a half measure is better than no measure.

My employer requires alphanumeric passcodes. So you can’t do it single handedly.

It’s also pretty moot in a customs environment. If you use your phone, chances are there’s a camera angle on your pin entry, and they have tools to crack numeric passcodes.

I'd argue it's not extreme enough: Use an alphanumeric password or passphrase, as long as you can tolerate, instead of a PIN.
