To me it is more of reducing a surprise factor.

Some people use "S11" prefix for Soap, some use "soap" prefix, some use "s". When I tell them the choice of the prefix affect canonicalization they are surprised.

It is the same logic as whitespace in content. People always think that canonicalization will remove the whitespace, but it doesn't.

A very old draft version of canonicalization used to have prefix rewriting - see http://www.w3.org/TR/2000/WD-xml-c14n-20000119.html#sec-namespaces
But later version removed it see http://www.w3.org/TR/2000/WD-xml-c14n-20000601#NoNSPrefixRewriting, because of the QNames in content problem. If we can solve the QNames in content problem at least to a reasonable extent, then we can reintroduce the prefix rewriting.

Sure, probably more than two. What's not clear to me is how rewriting
prefixes addresses any compelling use case other than "JAXB is broken".
