Yes, writing the initial version is one thing, but keeping it alive
is more work and more important.  As the underlying API changes over
time, it will become necessary to update the sample implementation,
but for a newbie who wants to learn by building "walken" on top of
the then-current codebase and API, it would not be so helpful to
show "these 7 patches were for older codebase, and the tip 2 are
incremental updates to adjust to the newer API", so the maintenance
of these sample patches may need different paradigm than the norm
for our main codebase that values incremental polishing.
