One of the BIG disadvantages of CSA is that too many programs are spending too much time in Key0 and it is all too easy for them to splat all over someone else's product anchor block.
I would like to be able to allocate my anchor block in CSA64 and feel safe that only programs with correctly registered interest can alter it (key0 or not). Personally I try leave my code in key0 about as long as I would leave my 4 year old son with a carving knife.

Obviously I can see the benefits of true CSA64 - but I would like the option to making it READONLY to all by default.
