Comment (by jpflori):

 I'd say the change is needed.
 But that's because the code there uses an internal method to go faster
 rather than the publicized safe and slower method.

 Normally one would use the public and slower method and won't have such
 problems.
 If one wants to use internal stuff, then it does not sound so unnatural
 that one has to be careful.
