It's a strange shift and one I've fallen into the trap of. Discord requires kernel extensions for screen sharing and requires the reduced security toggle as a result. I've gladly used screen sharing in the past with presumably the same mechanisms, and not thought twice about it.

Yet for some reason I'm hesitant to reduce the security of my main personal machine, even if that 'reduction' results in a consistent level of security with my old 2015 x64 MacBook. The reality is that I probably need to go and determine if there are a greater volume of more prevalent kernel level exploits to figure out what the factor of risk really is - it may be that these features are exploited more regularly and to greater effect than they were in 2015.
