Installations but for minecraft

lets be honest here, whats more frustrating, losing months of work in modded worlds, i would like for us bedrock players to have a similar wayback machine like in java so if we want to and want to play older versions we can go back to lets say 1.20 or even further back, iv lost months of work and without even being able to get newer versions because the devs dont update addons so i would like a new function for people like me who want to play older versions and with friends of course
