If there is some way to split the patch properly while avoiding
regressions that's certainly best.

I guess I assumed that there is no clear way to do that and the tests
temporarily breaking are somewhat edge cases (i.e. the functionality
loss isn't really an issue in practice). If that's not the case then
sure, todo_wines would be "cheating"...
