Really hate these kind of changes. You can remove anything in the name of security, if you claim your users to be stupid enough.

Actively stupid in this case, I presume. I mean, wouldn’t they need to go into the settings themselves and manually switch it to another app? (And if this is not the case, then why not change it to require that?)
So, they would not only need to be stupid, they would also have to be smart enough to go into the settings and change this option. If they manage that, I don’t think, you can stop them from shooting themselves in the foot.
