Certainly $Id$ keys are rather useless as long as the file is part of a
managed repository. However, files escape into the wild.
Outdated or incompatible file/software versions are a major source of
errors. I would suggest to keep that in mind before removing version
information from files altogether.
(On a similar note, I would again suggest to introduce version
identifiers for Isabelle theory files, to acknowledge the fact that
their syntax is evolving from one Isabelle release to the next.)
