It is very unlikely that the actual threats you face make this "an important distinction". If you don't have 24/7 bodyguards, it's time to be realistic with yourself that in fact "I got drunk and clicked something dumb" or "That wasn't a real email from FedEx, what was I thinking?" are much bigger threats than "A covert team picked the lock on my condo and then while I was asleep they modified my MacBook to help them break into my GitHub account".

Because biometric security in these scenarios is local the bad guy needs to steal the device first. Again, it is very unlikely your threats look like that. Real crooks who steal devices like MacBooks or iPhones will sell them to some dodgy bloke not try to impersonate you and break into your GitHub account before you invalidate the keys.
