Closes #1567 The main reason I'm not simply merging Annika's PR is because this way makes it clearer that I'm taking responsibility for all this code, that it's mostly code I wrote, and also because it makes it easier to ensure that none of the files have been changed. (Not that I don't personally trust Annika, but I have something resembling an obligation to users not to expose them to risks based on personal trust.)
