Even within the SW universe there were limitations on the practicality of this strategy: (1) a large enough mass relative to the target so as to cause enough damage, (2) enough armor or shielding for the sacrificial mass to get within hyperspace jump range of the target, (3) a very limited window of space in which to actually hit the target while making the jump to hyperspace, and (4) a crew willing to sacrifice itself in such a manner (because droids and others couldn't simply be ordered to do something like this within the cannon of the SW universe). But more to the point: we don't know if the Holdo Maneuver became more common in the SW universe because the only subsequent film decided to try and ignore everything that happened in the previous movie in favor of having space horses galloping on the exterior of a starship.
