too early, I think.

and memory is relatively cheap, compare to the costs of upgrade pain,
programmer time, and lack of optimization opportunities due to "bare
data structures".

yup.  I think a tool that generates cut-that-and-paste-this instructions
for the developer should be good enough, though, and fairly easy to
write, for the reasons you give.

that won't address the binary compatibility and optimization issues that
are the main rationales for my proposal, though.
