I agree that IPNS has always seemed a bit naff; but alternatives naming systems can be used too (if your system's name resolver can understand them); e.g. this uses pkarr addresses for IPFS content: http://www.chriswarbo.net/blog/2026-05-08-pkdnslink.html
Regarding an "update path", GNS has support for that built-in; though I've not been able to try it myself, since I can't get GNUNet to bootstrap :-(
I always thought that they should have used ENS instead of whatever coin they ended up making. GNS is cool but IIRC (years ago) it had no incentive mechanism which is I think where a lot of these solutions fall down. Even imaginary "ratio points" that p2p file sharing sites have being using for years work better than "donate your resources out of the goodness of your heart".
