For a bit of context.... Sugar is designed to run on low end hardware
to keep hardware costs down while extending battery life.

There is often a trade off between adding functionality and increasing
time and/or space footprint.  Thus, anything which increases
footprint, 'the cost', must be justified by improving functionality,
'the benefit'.
