Good job sir!
Each to their own, but I can’t see what the difference between a de-fretted neck and a neck made without frets is, granted it depends where your dot/markers are be they middle of the frets or on the actual fret - once you learn where they are, you know how to play it.
If there are no or very little bases fretless in the model someone wants, but a plethora of fretted ones, and the cost to de-fret is less than buying a whole new bass, makes perfect sense.
Buy a second neck and have one of each
