Hogwash.
Smart people don't beg for trouble. Always hire smart people.
...and your employer isn't hiring you for your personality. They have a job to do. They don't have any use for your "variability".
Why would they waste money on someone who they may have no interest in otherwise? In any case, you didn't have to comply. I told one prospective employer to take a hike for asking for something stupid in the process. If you don't like their policy, look elsewhere. That's what they're doing.
But (hopefully) not fried burgers.
