We are talking about changing the AST used to manipulate the programs.
Changing it (in either CIL or Frama-C) would mean breaking every
existing code around the world based on it. While it might be
acceptable in some cases, it is definitely a major change, with the risk
of alienating the user base. And if breaking changes are required
anyway, restarting from scratch might be cleaner.

It would not help Frama-C, because they forked CIL and changed it too
deeply to port anything but trivial patches between them.

Frama-C uses (almost) the same AST as CIL, with the same simplifying
assumptions that make CIL unsuitable for Xavier.

Thanks for the link. You should update the entry about CIL:
http://gulliver.eu.org/program_dev_check_environments#cil
to the new URL:
http://cil.sourceforge.net/
