I’ve designed a replacement bed hook that should prevent bed shifts in longer prints.
It’s a direct modification of the original STL, just with a slant on top.
One hook is enough - it will prevent the bed from shifting in the X-Y plane, while still allowing you to remove the bed as before when necessary. You just need to remember to lift it from the opposite side - the one between the original two hooks.
Since the top is slanted, it doesn’t impede the calibration nor leveling, at least on my printer. If, however, you experience issues, just bump up the piezo sensitivity a bit.
PS: Print it on its side (rotated 90 degrees), no support. PLA is fine.
