Custom Processors and Animation Curves

Are there plans to support AnimationCurve fields for custom input processors? In 2020.1.3f1, adding an AnimationCurve field throws the following error for me:

Code (CSharp):

1. ArgumentException: Don't know how to convert PrimitiveValue to 'Object'

Edit:
After trying some other stuff, looks like the InputAction asset editor window doesn't support property drawers of any kind. This would be useful to have to enforce value ranges etc.
