I'm curious how that implementation addresses the issues I

I'm not really sure how to respond, you mostly just made
statements about your worldview. For instance:
"C++ on a 64K machine is like using a tank to get to the
grocery store". If you mean using all of C++ features, sure,
that's inappropriate. If you mean that there are no C++
features that you could use in a microcontroller, there are
non-trivial amounts of people the disagree with you.
You can't use RTTI or Exceptions, for example. Those generate
bloat even if they are not used - a compiler switch is typical
to disable them. It's not true that C++ is "pay only for what
you use".
If the C++ usage is "C with member functions", then yes, it'll
work and be useful.
There's more to that. Since these chips have limited
computational capabilities, you really want to move as much
computation as possible into compile time. And this is what makes
C++ a better choice than C, and D a better choice than C++. It's
also the safer and more expressive type system that saves you the
time you would spent on debugging every kind of bug resulting
from casting everything to void* and back.
