12 Ga wire is just a waste of time and money.

A 20 amp breaker would not be allowed to feed most of the lamp fixtures
anyway, with their #18Ga internal wiring, let alone get the #12 under a
screw head terminal that is not rated for the mechanics of it.

The #14 wire is way over engineered already for the recommended max device
rules etc.. and now people come along and try to use a safety factor on top
of all the safety factors built in?

Usually, following recommendations and minimum requirements are the "best
practice" from a century of engineering design and field experience.

Having said that, many long runs should have #12 used for voltage drop in
ling houses.
