This is moot to the issue of the CC0 license.

One of the reasons we've not been worried about it is that 35-40 year period. But we/are/  going to hit it for the Numerical Electromagnetic Code (see Wikipedia) and other Academic software that has derivatives still in use.

Section (1) requires a large enough majority in a joint work that most community-developed products could never be recaptured, as far as I can tell.
