@Sebastian-Roth Didn’t has time, sorry. The whole PLUGIN thing was actually new to me, so now after quick navigation in settings, I’ve explored PLUGINSYS checkbox. 
Thank you, now I’ll sped some time to investigate all of the “mainline” plugins. Thank you for advising me to use this plugin.
PS
Aaan,d I could’t find any functionality that I’ve implemented, also the whole thing seems not working, because I couldn’t restrict Support role from accessing “Access Controls”, where they can revert everything back.
I also reported to this topic about last problem: /topic/10918/access-control-plugin/10
