Parental controls

Apparently the universal parental controls addon I have relying on for years no longer works and has been discontinued, my Old kodi 17 installation with the addon stills works, but I am unable to install a new one using the addon.

How do everyone solve parental controls? I google and search the forum and I see no good options.
Sorting files in different folders is an example of a bad solution.

The video-node and profiles in the wiki are quite poorly explained when it comes to limiting movies based in movie-rating.

The issue is not limiting addon usage, I found some addons that do that, the issue is preventing my kids from watching movies not intended for kids their age, I.e. requiring a ping for PG-13 and above movies.

Any ideas?
