I was wondering about that too (see [1]). My only concern is that some
extensions out there might be accessing the string expecting it to be
properly truncated. The rename at least forces them to look for the new
name...  I'm slightly in favor of keeping the rename, it doesn't seem
likely to cause a lot of backpatch pain.
