Well technically there was a Magic Band 1.5 that was just about as flexible as the 2.0. Oddly for smaller wrists the 1.0 was less wide across the width of my wrist and fit better. I have kid sized hands (literally the same wrist size and slightly smaller finger size than my 9yo) and they are not good at all. I take it out and use a keychain though.
here are pics to show on my kid sized wrists.

(what I call the 1.5 on the left)
Showing how much wider side to side the new ones are even with edges removed
Not comfy in the least to me or my 9yo. At least the 9yo will grow LOL
And just to show, the three on the left are what I call the 1.5 and the other two are 1.0s. They are all set to the same size (same hole position). You can see that the newer were 'taller' than the older. They were thinner top to bottom and more flexible too
