There were times on 360 where games came out a few days early (I remember fondly with KoF 2k2 UM). Most of the time, all online activities were inaccessible until the Day 1 stuff came online. Noone got in trouble with early downloads, but early store copies sometimes made issues.
Strider on Xbox One went up early by about a week, because the game had to be available for press to download, but the links were to be inactive. However, people were able to access the game by finding a press person with play history, and launching download from that.
After 2 or 3 days, Microsoft made the game inactive until release day. But otherwise, they didn't force a file delete or anything. Wouldn't be surprised if something like that eventually happens here.
