Exception safety does not necessarily require RAII. It depends,
case-by-case. Sometimes, one can mix large parts of code which is
too expensive to 'convert' to RAII with wrapping code that RAIIfies it.

I agree that RAII, or close to RAII, would be a reasonable goal: what
I'm saying is that does not happen in a glimpse and you have to live
those couple of months/years plus bug fixing with non-RAII code.

Do you know a QuickRAIIFierTool download page? :-) I'm half-serious,
one should write code transformation tools such as this one.

I must learn to use this metaphor...
