This is a good thing for the health of the GNU ecosystem, and I hope other GNU projects adopt this practice.
Related story: a couple of years ago, the current maintainer of an Emacs package reached out to me. Apparently the FSF wanted to make it part of the official Emacs distribution, and wanted me to assign my copyright to them. I was happy to do so, BUT: the code was written more than 20 years ago when I was at university, which (according to the FSF) meant I needed to get a copyright release from the university, in a country I no longer lived in and that I had not interacted with for literal decades. This seemed like far too much trouble at that point, so I gave up, and the package never became part of Emacs.
