This seems to be an odd position to take in a thread about kernel extensions given that they're a fairly esoteric feature that power users make use of.

But 'power users' and 'audio professionals' aren't necessarily the same people.

They're fairly common on the Mac, even for average users. A 3G mobile network dongle I got from Virgin Mobile required a kernel extension to run on my Mac.

Of course, years later I'd be much more hesitant to install a required networking Kernel Extension from an organisation called "Huawei".
