If you're going to pull this, you need to know in advance that it's necessary, that's not some minor thing that everyone is going to just do automatically, it's an extra, complicated step it's easy to screw up.

That said, I acknowledge the possibility of compromise in the aforementioned scenario, but once again I don't understand people who always jump to the "I am vulnerable to this narrow threat model, ergo, I should not bother to protect myself against any threat models". Especially when the measures you can take to protect yourself most likely will address the actual threat models you are liable to encounter.
