You transform *into* the encoding, and untransform *out* of the encoding.
Do you have an example where that would be ambiguous?

You can ask the same question about all the other codecs.  (And that
question has indeed been asked in the past.)

(One answer is that they used to work in Python2...but the longer we go
without restoring the functionality to Python3, the weaker that particular
argument becomes.)
