I always close a document without saving if I come across such warnings.

With just one saving, the backup copy (mybook.lyx~) will still contain the
custom environments. So a `cp mybook.lyx~ mybook.lyx` saves you the tedious
hand-reverting.

I also vote for a more save handling of such automatic conversions
that can indeed delete lots of information from the document.

This is a nice idea, I hope it is easy to implement and look forward to
see it in the next version.
