Personally, I would wait at least for another completed checkpoint before
deleting a savepoint but from what I read, I would probably also always keep a
savepoint around to recover from. I guess that depends on the availability
needs and storage capacity that you have.
Maybe @StefanRRichter or @StephanEwen can elaborate a bit more on best
practices there and extend the docs accordingly.
