This datapack automatically disables every Parcool ability for each player using advancements, as soon as the player joins the game. It uses the minecraft:tick trigger and is only run once per player. After the advancement is given, it is not run again.
Therefore, you are able to grant players their abilities back using whatever means you'd like (manual commands, KubeJS, a datapack function, FTB Quests command, etc.)
The datapack shows all of the disabled abilities in the Advancements tab. (If you don't like seeing them, you can delete the display tab for each ability's JSON file in the datapack)
Only tested on 1.20.1, but might work on later versions as I don't believe there are any changes besides datapack version number.
It's a little rough around the edges but it should work fine.
