Current umpires maybe. Former ones... much less likely. I'd not expect a current umpire to go too far out on a limb but you also wouldn't see too many current umpires agree to speaking publicly about a controversial call.
Nonetheless, it doesn't mean he's not being sincere in his belief it was correctly applied. My point last night is that there really wouldn't likely be too many umpires that applied this rule differently than it was applied because they're all taught how to apply it and it doesn't match what the public expects of the rule.
