Curves = Mesh!

It feels like the curves were created from 0 just to be ... They should have most of the capabilities that are available to the mesh if they were just forgotten. Such as: Vertex color. Vertex weight. Some modifiers. Physic.

My suggestion is to cut out this type of objects completely and create modifiers like: curve bezier, curve, ..., curved plane, ...

What for?

-Why geometry, selected in a separate type (curve), has the necessary functions, when as a mesh does not have modifiers for high-quality fake curves. And at the same time, the type of curve is not completed. You simply cannot work with curves with restrictions that are simply not logical /
