Hi, while we love to hear these ideas, this is not the right place for them. This website is mainly used to track bug reports and not feature requests. But luckly, there are some other nice solutions you can take, so please use one of the other forms of communication listed below:

• Fun board mailing list: https://lists.blender.org/mailman/listinfo/bf-funboard

That being said, you can use CurveMapping in python, see e.g. stackexchange
User can manipulate the curve and you can read/evaluate it. Dont think you can write your own CurveMap points though (if this is what your request is about specifically)
