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

If you have visions of becoming an electrician, don't quit your day job.
The "internal wiring" of a UL listed lamp fixture has no bearing on
breaker size. If it did then those fixtures would not be allowed on a
15 amp breaker either. The general rule is that the breaker is to
protect the circuit, not the device served by that circuit.

let alone get the #12 under a
screw head terminal that is not rated for the mechanics of it.

Would you be kind enough to identify a UL listed light fixture currently
on the market that has screw head terminals that will not take #12 wire?

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?

Yep.

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

Nope. The code is a _minimum_ standard. No inspector is going to fault
an electrician for _exceeding_ code. I wish that code had been exceeded
in my house--they wired it all with 12 gage aluminum, barely meeting
code, which I'm slowly replacing with 12 gage copper.

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

Whatever a "ling house" may be.
