This sounds like a good plan to me.  I can understand Jack's concerns
about input, but it's really common for software to fail on a really
messed up save file.  I think once you hit the point where a session
file isn't recognizable, you're totally correct in not being able to
load it.

I also think that this is a good move.  Until something called "stable"
is released you shouldn't have to be tied to a specific format.  This
has happened twice to me, but in both cases, there were simple scripts
availble that fixed older session files.  Witness how many times the
on-disk format for ReiserFS changes in a development cycle for a
comparison.
