Smart bone and animation

[Hamedss]

Hi.
I thought that all animable parameters can use with smart action but noticed there are some parameters that are not so! Even the next parameter to them can be used in smart bone action. For example in Layer setting , Layer effects, "Auto Shading Radius" can animate in smart action but after back to main line it will not work but layer blur work as well with no problem.
Here are some other parameters:
Outline and colorize layer
All layer shadow setting in shadow tab
Motion blur settings
Bone physic settings
Wind parameters

I wonder why they seems working in action but not working in mainline!?
