It pops up whenever you need to detect the encoding of the
incoming XML data on the network connection, e.g. in XML RPC
or data upload mechanisms.

Even though XML data mostly uses UTF-8 in real life applications,
a standards compliant XML interface must also support other
possible encodings.

It is also not always feasible to load all data into memory, so
some form of buffering must be used.

Since incremental codecs already implement buffering, it's only
natural to let them take care of the auto detection.

This approach is also needed if you want to stack stream codecs
(not sure whether this is still possible in Py3, but that's how
I designed them for Py2).
