Oh, no, not at all. I just feel that sometimes eliminating constraints is not the right choice; there's sort of a tension between freedom and focus/clarity etc.
ETA: though on further thought, the question of their instrumenthood is in there at some level, I must concede. But it is quite a complex notion.
e.g. is a fully chromatic mountain dulcimer still really a mountain dulcimer? To what extent is an instrument indivisible from its canon/repertoire?
Certain classic pieces of folk music may never have evolved if the early instrument had more freedom to fret more notes, because an entire style of playing the dulcimer (the "noter" style where you fret with a small stick) really is rather interwoven with the diatonic layout.
Like I say — there's no hard answer but I think this is a question musicians often grapple with as they develop their talent more deeply. In the same way that a lot of guitarists at the top of their ability abandon a lot of the anciliary kit (effects pedals, particular instruments) and strip back.
In the AI era I spend quite a lot of time thinking about creativity and constraints, but it has always been fascinating to me.
