The company I work for has been converting from CVS to SVN and one of
the things that both CVS and SVN do (although SVN requires a 3rd party
tool to really show it) is provide information on which branches a
particular change in trunk is present. This is incredibly useful when
tracking down bugs from support escalations.

The problem with DVCS that use separate repositories to represent
branches is that it becomes very hard to find this information because
the tools are only aware or can only operate on one repository at a
time. Git and Mercurial are not so bad in this regard because they can
have branches in repositories and you can track the history graph
through their graphical log commands, but Bazaar currently does not have
this capability, as far as I know.

Ciao,
Gordon
