Why exactly? A lot of people's issues with uEFI seem to stem from Secure Boot (and the lack of additional CAs contained within). And while I grant that Secure Boot is problematic, uEFI is actually taking us away from black box firmware that was BIOS.
In many ways this type of stuff has always been possible, the only difference is the skill threshold has been lowered. So I guess the question is do you believe in the phase: "Ignorance is bliss?" Because that's what you're asking for, back to BIOS where these things are still readily do-able, just requires more technical skill and time.
