It's a true feature. You explicitly fixed that feature in
revision 1.20

Restore Python 2.1 StringIO.py behaviour: support concatenating
Unicode string snippets to larger Unicode strings.
This fix should also go into Python 2.2.1.
after you broke it in
revision 1.19

StringIO patch #462596: let's [c]StringIO accept read buffers on
input to .write() too.

Correct. That still doesn't make it an implementation detail.

Then why did you fix that behaviour when you broke it?
