Please don't make such glib uninformed comments: https://youtrack.jetbrains.com/issue/IDEA-341408/Disabling-p...
THE OLD VERSION IS ENABLED AFTER IDE RESTART.
1. The enabled plugin prompts you to 'activate' the service
2. If you do not activate the service the plugin is enabled but does not use the service
3. There is a minor bug, allegedly (have not reproduced it, and others have tried and failed) where the plugin can be disabled and then it re-enables itself.
