Try to "dot i-s" in a long word and see for yourself. It's just awkward. So people compensate by using thicker strokes that hide that "floating" effect.
I'm studying Chinese, and writing the characters is pretty much the only way to learn them. So far, the only device that semi-worked for me was a reMarkable 2 tablet. But its software is too shitty to be useful.
So I just switched to paper completely.
But for writing in English and many other languages, it seems like this doesn't present a huge challenge. I am particularly interested in (but have not yet tried) the handwriting cleanup feature. This seems like a nice middle ground between full digitization and leaving chicken scratch as-is.
