Wouldn't it be better to have the code potentially broken _now_, when
they're (very) _early adopters_, versus in 2-3 years when *everybody's*
code would break?
There are dangers to being an early adopter. One of them is having to
rewrite code when it becomes clear that certain method, discovered during
the early adopter phase, is not going to work in the long term.
Better to break 1000 people's code now than 100000's in two years.
Or are we just playing time here? If we can delay this enough, there's no
way we can get rid of mapped addresses in the next 10 years as it's going
to be used by ported apps more and more...
