For example, instead of letting the user add any border-radius value, we’d have named classes under the hood like rounded-sm, rounded-md, rounded-full, etc. Then, theme authors would define what those values actually are.

I had just filed an issue asking for something similar! The font size presets strike a great balance between user and developer control.

Has the Gutenberg team really dismissed this approach definitively? 🤯 Do they not see the many problems with block settings outputting inline styles?
