This is addressed in The Rise of Skywalker.

A Resistance character suggests using "the Holdo maneuver" against the First Order, but another one dismisses the idea, saying it's a "million to one shot". It's not addressed further, but we can surmise that it's not guaranteed to work, so can't be relied upon as a usual tactic.

This is (somewhat) addressed in The Rise of Skywalker.

A Resistance character suggests using "the Holdo maneuver" against the First Order, but another one dismisses the idea, saying it's a "million to one shot".

It's not addressed further, but we can surmise that it's not guaranteed to work, so can't be relied upon as a usual tactic.

The Visual Dictionary gives further detail, in a section about The Last Jedi:

Vice Admiral Holdo perfectly times a devastating point-blank hyperspace jump so that her massive warship, the three-kilometer long Raddus, intersects the mass of the Supremacy at lightspeed before her ship fully enters hyperspace. The resulting collision cuts the Supremacy in half.

(Star Wars: The Rise of Skywalker: The Visual Dictionary, page 28)

So it seems that the tricky part of the maneuver is timing it just right: the piloted ship has to be traveling fast enough to cause damage, but can't have entered hyperspace yet. Since getting a ship in the right place at the right time while traveling at lightspeed would probably require very high levels of precision, this offers an explanation for the maneuver being difficult to pull off.
