No need to yell.
But it is correct, when your sysnand (3.0.0 or higher) starts up your 3DS, it locks access to the OTP area, so lonnng before you can even start EmuNAND.
Why it would still be great to have 2.1 emunand is that it allows you to boot the emunand, see if it's alright, shut down and dump your emunand, rename it and flash it to sysnand, then restart again to dump OTP. Right now after downgrading your EmuNAND to 2.1.0 you still have to take the Leap of Faith to flash it to sysnand untested.
