ENOENT means that there is no userdata associated with the relevant domain and key. This is not an error condition. And it is deliberately possible to manipulate other toolstacks' domains from xl. You get to keep all the pieces. If you want to make this fail, then a safety catch might be OK but it should be in xl not libxl and I think the manipulation should be allowed by default.
