Thanks for showing the examples what can be seen as generalization, this
is quite wide subject:

On osm-carto we also use types generalization (like meadow and grassland
shown in the same way), which is very different than the one in the
original message.

I don't think this is true. For example making borders simpler increases
clarity, while previous state was creating optical illusions.
