A solution to NOT drill your track forks and have a normal front brake nonetheless

A star nut isn't the best of both worlds...an expanding wedge is, and i don't mean a quill style wedge.

The types used for carbon steerers make the most sense as they expand evenly all the way round unlike a stem style wedge quill, but they also allow tensioning against the base of the fork like a star nut whilst still allowing complete removal without resorting to hammers and scoring the inside of the steerer.

True. That might be interesting as well.

But keep in mind that the ones you mean do not 'cut' themselves into the material (which is why they are suitable for carbon), therefore are not equally strong.

The cutting and scoring isn't a problem at all if it's a steel steerer, aluminium is a different story, yes.
