In its default state i think thats fair. Example docker bypasses most firewalls as it runs before iptables rules process. So if you don’t either use 127.0.0.1:port:port (many compose files offered by projects do not do this) or add specialized iptables rules to fix that up you can end up directly exposing services with meaning to or even realizing.
And yeah privilege escalation etc. There are solutions like what you mentioned but it can be a lot of work to set all that up so most people won’t



No but there is a semi work around.
When using the app if you select all images one of your options will be delete from device when you click on that it will say hey some of these might not be backed up and one of your option is to only delete the things that have been backed up. It’s not automatic but it is a way you can kind of just Mass do it to everything
