In theory, sure, that's what we'd do in an ideal world.
In the real world it will take millions of dollars of eng labor just to update the hashes to fix everything that's currently broken and millions more to actually implement something better and move everyone over to it.
This isn't worth it, GitHub needs to just revert the change and then engineer a way to keep hashes stable going forward.
"The amount of work done “out there” on hundreds or thousands of applications for a single little libcurl tweak can be enormous. The last time we bumped the ABI, we got a serious amount of harsh words and critical feedback and since then we’ve gotten many more users!"
I know it's superficial but I think the problem would have been reduced if they used a download URL that looked like github.com/archive.php?project=rust&version=deadbeef it's just something that sends a signal and a different expectation on the same artifact.
