jordanjay29 interesting suggestion. Flarum is however moving towards a stable release, which is an asymmetrical movement. Recent studies state that an "uneven distribution of mass and charge in the nuclei causes the isotope to ‘point’ in a certain direction in spacetime, and the team suggests that this could explain why time seems to to only go forward and not backward".
So any asymmetrical movement, like moving to a stable release, disallows any jumps back in time. We could however decide to work on different versions of Flarum simultaneously to mitigate asymmetry and prove that time travel is possible.
