@Simon, finally, in reading the patch this will affect both strict and
devmode and so the patch should "if startswith 'snap.' and process is in
enforce mode ; then block recording".

This will be needed for the phase 2 implementation as well, so it is not
wasted effort. I've asked the apparmor devs to comment in the trello
card if there is an apparmor API for this. Be cognizant of TOUCTOU here
but also understand that a snap is not able to change its enforcement
mode so a TOCTOU is not security relevant for this particular change.
