Is there yet a movement where artists and creators make a testament that after their death all their work becomes public domain? Ie. an explicit middle ground between default copyright period and immediate PD at the time of publication?

I'd be interested in developing and advocating this kind of movement to widen the common public cultural legacy. But I guess some sort of legal expertise would be good to have. And if this is already a thing, then great, I'll join!
