I'm not an expert on it but what I understood from Jason on why they (as I understood it) removed all JAXB parsing was that
a) it was too slow b) not flexible c) the code got very messy to support multiple versions/variations (probably related to b)

This was in comparison to the stax(?) parsers they moved to as far as I understood it.
