I would like you to call for action. As far as we know, variable fonts have immense possibilities within animations. However, most used software for the motion design hasn't even touched the idea.
As far as I know, the most voted open feature request has about 500 votes. And as closely we chase that number, such likely will be Adobe engineers convinced to at least consider the feature request.
So why don't do it?
(I am not sure about the expression "as closely..., such likely..." expression, excuse my grammar defects)
