I read an article on the next update of Catalina 10.15.4 will depreciate all kernel extensions. I have a test system of 10.15.2 that is working OK.
Apple kernel extension APIs to be deprecated in macOS 10.15.4.

Could anyone comment about a pre-upgrade strategy that will mitigate problems.
It has been suggested that "If you use macOS, run kextstat | grep -v com.apple to see how many third party kernel extensions you have running".
I am more interested in the effects of booting than I am of some software programs not running.
