I think that it would be handy if there was the possibility to disable node attributes in a way that:
- they would not be displayed anymore in the module’s “Layer Properties” window
- they would be hidden in the timeline.
This could for example be set via check boxes in a “Publish Attribute Mode”-like mode in the “Layer Properties” window.
Indeed, it is perfectly possible to block attributes by using expressions.
But, this still might confuse animators unfamiliar to expressions. Attributes just not being available might add more clarity.
