What exactly is involved in maintaining it in the trunk itself ? Would such
maintenance require more than one person ?  I just do not see how the
out-of-trunk maintenance is supposed to work. For example, if a 2.3 version
of QtWebKit was supposed to be released from such branch, how would that be
treated ? Would it be considered an official update of QtWebKit for Qt4 ?
