Two (not necessarily great, as there is a tradeoff) ideas to assist with

- Isabelle version headers in theory files (e.g., "Developed for
  Isabelle 2009"), possibly with Isabelle issuing a warning if

- More tool/script support for automatic updating of theories.  (Similar
  to "isatool fixheaders", etc.  From an end-user's perspective, an
  automatic tool that could simply update current theory files to work
  with the next Isabelle version would probably be ideal.  Of course
  such a tool might be too difficult to develop though.)
