Installing a light build can be done by (most) anyone, without any special
skills, licenses, or tools, and at zero cost (other than the light bulb
itself, obviously)

Any other option requires a licensed electrician, and comes at a
significantly higher cost..

The "temporary" installation also has benefits as technology changes and
matures.  Anyone that installed previous generation hard-wired controllers
(eg, z-wave) may currently be in a position of running devices which known
security issues, and no easy way to replace them.
