It seems that every Youtuber machinist has a video on making toolholders. Take a big block of steel. Cut the dovetail down the whole thing. Chop to individual length. Mill a slot and then drill and tap holes. Then you use the drilled-tapped holes to clamp a bit holder in the slot.
Those last couple of operations are quite a bit of work. When using carbide tooling, wouldn't it make more since to mill a landing directly on the nose of the holder for the bit? The point of making the holders in the first place is so that you can have a separate holder for each tool. Why not skip the extra steps and end up with a tool that will be much more rigid at the cutting face since it doesn't have to transition through as many connections?
