Allow Pistons To Move String Without Breaking It (Redstone)

This is a fairly small thing that would be useful and could be added in 1.17. Quite simply, allow pistons to move string without breaking it. This would be most useful it flying machines and other piston builds, because the string could act as an air block to players, but still count as a block to pistons, allowing mobs and such to be contained within a moving structure more easily. If possible, it would also be extremely useful if containers could be pushed, and if redstone components (redstone dust, repeaters, comparators, redstone torches, ect.) would not pop off, possibly allowing for the fabled 6 way flying machine that does not require stations.
