Thanks for writing this. I'd only been loosely following it and I hadn't realised how bad this is going to be. I have repos with tens of submodules and it's going to be a nightmare if any of them switch to sha256 in place. Not to mention I won't be able to use any new projects unless I rebuild my repo and all the submodules therein.

I thought the master to main thing was bad enough but this is going to suck. And just like the master rename it achieves basically nothing.

What is it about these projects that attracts people who just want to change things for the sake of it? Real engineering means coming up with a solution for backwards compatibility. This is just irresponsible and, frankly, a fuck you to everyone who will be affected by this.

« people who just want to change things for the sake of it » — Not for the sake of it, but to “make the world a better place.” The intention is noble (well, mostly, at least let's assume it is). Of course, there is disregard for history and her deplorables (or not so deplorables), comes with being “progressive”. Which is why I like Windows better (not 11 though, will probably have to go back to Linux at some point).

« What is it about these projects » — Maybe that they're “at the forefront.”
