This note from the manual is a bit vague:

   Note that the streams can be replaced with objects (like io.StringIO)
   that do not support the buffer attribute or the detach() method

"Can be replaced" by who? By the Python developers? By me? By random
library calls?

Does it mean the buffer and detach are not guaranteed to stay with the
API?
