Random theoretical work arounds like this bring no real benefit at all because:
* it is no good if you don't use the functionality
* if you always use it, your life will be very impractical
* if you want to use it when you suspect you have malware, well, since malware does not announce itself, you are really not protected from anything unless you preemptively know when there is malware, which if you can do that, you probably don't need this
Theoretically yes, this can be a useful, maybe...
