Bedrock - Adding a datapack should not enable cheats / disable achievements

I tried to add a datapack for one person sleeps, like the java edition datapack. it allows one person on the server to sleep so that everyone doesn't' have to at the same time. 

When trying to load the datapack, it required me to disable the achievements. so naturally, i didn't make my world better because we do like the achievement system. 

Please allow us to change more game rules and add features without breaking achievements, or give us the ability to add datapacks and some mods without turning achievements off.
