@alikon nice work here. If I may I would like to propose another approach with less db stuff. We could use a reflection here to reset the plugins, in run time, similar to https://github.com/dgrammatiko/jailed-fs/blob/95444d8778e930a0360740e3b511b23bde374a5c/src/plugins/system/restrictedfs/src/Extension/RestrictedFS.php#L68-L78

You need to figure out what is essential and create the correct filter but should be an easier approach, ie not messing around with the real data in the db...

Also, I would use a URL parameter, ie joomla_safe_mode=true that will be checked by the plugin, together with the user permission, ie only users in the administrators group to activate the safe mode.

@dgrammatiko let's see 1st if it gets a consensus

ouahhhhhh great toooool, an idea for futur add step in upgrade to switch automatic to safe mode during update and propose to disable safe mode at ending process. That can be cool to protect upgrade process

Not sure if it helps, but HA has also such a "feature".
