This is how I feel reading the above:

Here's why:
You have the option to use any authenticator app you want, so you could split the accounts over several apps.
There's several desktop based auth apps too, which means you could spread out the acc auths over several devices too.
I know you're saying it because there's some seriously stupid people out there and they'd probably put all accs on the same auth and then get deleted on all in one go.
But you shouldn't have to recommend something that doesn't really make a difference... unless the person reading the recommendation is stupid and didn't think about using several apps/devices.
