Agents of S.H.I.E.L.D. Season 6 already established that time loops could be broken, but what other time-travel rules are there?

In a newly released Season 7 video, Daisy reveals that she’s worried about the butterfly effect.
After defeating Izel, an ancient entity, the S.H.I.E.L.D. agents barely took a moment to revel in their success before being thrown into an entirely new situation.
