Because it might save your life someday (been there, helped me).
This is the difference between being able to recover and having to
install the base system again after some types of failure.

It is *faster*? How did you measure? What is the memory impact? Did you measure
that as well?

Disk space saving is obvious. The other points are more subtle and I would
not bet on any overall figure without good measurements.
