// There are way too many possible errors.
// Examples are various git errors such as the commit the review was based on was gc'ed and hence doesn't exist anymore as well as unrecoverable errors where we should serve a 500 response
// Due to the current architecture and physical limitation of needing to compare explicit error messages, we can only choose one approach without the code getting ugly
// For SOME of the errors such as the gc'ed commit, it would be best to mark all files as changed
// But as that does not work for all potential errors, we simply mark all files as unchanged and drop the error which always works, even if not as good as possible
