As a real world example, the aim is when building an ipk based image,
only the do_package_write_ipk tasks would have their sstate packages
fetched and extracted. Since the sysroot isn't used, it would never get
extracted. This is another reason to prefer the task based approach
sstate takes over any recipe based approach which would have to install
the output from every task.
In case anyone cares, the "per-recipe based staging" used in OE-lite,
and proposed as a future design concept for OE-core (although clearly
not going to be used in OE-core anytime soon) is also task based in the
above context, and has the same advantage as described for sstate above.

I just wanted to make the point as the "any recipe based approach" could
easily give casual readers the assumption that this was a weak point in
my proposal.
