They're two completely different codebases... even if they are 100% feature parity, it's 100% different code. They should absolutely be separate from each other, with different issues lists. Clean separation of two different codebases isn't a strange concept...

Right, but it's my understanding that it was done as a PR that was merged to `main`. Sure, anyone could find the last Zig commit and branch off of that, so I guess it's all po-tay-to po-tah-to.
