Hackintoshes are definitely flakier but mostly due to breaking changes in OpenCore or your boot method, which you want to keep patched so you don’t have issues with macOS updates. If your environment and threat level allow it, you could simply not update once you get a stable config, and just image the entire boot drive. As long as your UEFI config doesn’t get corrupted, you’re fine. I’m sure that could be saved as well through rEFInd or similar tools.
Once you’ve assembled this house of cards, it’s fairly stable, I assure you. Just don’t look at it sideways. :P
