Should this read "non-essential" amino acids?
"Essential" aminos are those that cannot be synthesized in the body from
other aminos and must be eaten in the diet. "Non-essential" aminos are
those that can be synthesized in the body from other aminos and do not have
to be eaten in the diet.
I think eliminating some "non-essential" aminos in the diet would lead to
more synthesis of new aminos from other aminos and the synthesis of new
proteins. Eliminating "essential" aminos would cause a deficiency that the
body could not recover utilizing other aminos.

Yep. They are not totally deficient in any one, but there is a definite
limiting factor where some are represented at much higher levels than
others. Beans and corn are both "incomplete" proteins which can be combined
together to form "complete" proteins, but the body would have to put them
together. (Nutritional labels only show the "complete" protein portion.
The "incomplete" portions are not reported. Combining beans and corn will
result in more complete protein being available to the body than the sum of
the two protein labels would indicate.)
I just posted some comments that my veggie diet might have this side-effect
of creating more new proteins, and I am intrigued about this PR idea. I am
not sure if the protein restriction is reducing the amount of protein the
body can produce, or if it avoids the condition of excess proteins being
available that are not needed.
