Expanding on it further, what I mean is that our BT stack should be built from ground up with security in mind. We cannot fight every attack surface but we probably can get to all the low hanging ones that the crims can exploit.

One day in some utopia probably.

I as a user of BT stack do not have to worry about whether it is switched on or off. This is what I mean by _secure by default_.

Downvoter - thank you. I took time to explain what I mean this time :)
