This is only a retro feature, which comes with its problems.
With Mercurial you have the whole history always around, and there is no
need to encode (tiny) parts of it in the file. Before source control
systems came about, people where used to have much more history on board.
Note that recent GNU Emacs will happily tell you the file id of the
current buffer, if available. Other tools like Netbeans also have
substantial hg support built into the editing environment.
The present plan about the old $Id$ artifacts is to remove them gradually,
or just ignore them for now.
