I don't think "new" has anything to do with the dialogs that have
gone on. And it's not HS physics if you want to really get into
it. You'd also need trig, calc and Field Theory at college level
to have a really good go at it! As in, there is no such thing as
a purely resistive or reactive load. Even a resistor has a
capatcitive/inductive component if you want to get picky enough.
I think the prevailing idea here was to keep the numbers going
in ways that the outcomes were perceptible, not negliglbie, and
interesting to boot. If it bores you, don't read it. Pretty
simple.
