This PR is focused on removing the list mutation. I recommend that we handle the not header["writeable"] issue separately if that's ok.

Merging on passed tests. @jrbourbeau can we schedule a bugfix release for this Friday at the latest? I'll resolve the writeable thing too. |

Yeah I was trying to prod CI last night, but I guess it still wasn't passing unfortunately (not that I think the failure is related) |
