it in the valleys and hills of Papua Niugini. And the Australian Aboriginals
never knew any such thing, nor did the Polynesians, though the Polynesians
were advanced in material culture enough to the degree of building the most
advanced stone-age ocean-crossing watercraft - to the degree they make the
Viking dragon-ships look quite primitive in some respects.

peoples like the pre-colonial Americans never got that far.

You ask, what is the most important thing?
Maku e ki, he tangata, he tangata, he tangata.
I reply, it is people, it is people, it is people.

Unless I'm mistaken, that sounds like the primitive way of obtaining lime
for mortar. Were the Mayan pyramids mortared??? I'd be surprised if they
were. (In pre-industrial Indonesia they burned coral to produce lime, but
small quantities. And isn't burning limestone basically the way cement is
made even today? Cement factories certainly produce a ton of smoke....)
The Mayans made heavy use of lime for stucco/plaster for covering their pyramids and also for relief work. The Rosalia temple under structure 16 in Copán is an example (it was buried under a larger temple and was intact -- stucco work and even the colors).
When you burn limestone, you get quicklime, which is essentially what plaster is.
For actual building cement, you heat limestone and clay together until they almost fuse, then you crush it into a fine powder. When water is added, this gives cement.
Mayan pyramids were essentially big mounds of rubble faced with limestone blocks. They would often frame off the site, wall it in and then fill it in with rubble, then build another level, and fill that in. After they constructed the building, they'd then coat it all with plaster and then add any ornamentation and plaster work to the outside. They'd also paint the sculpture too (as is the case with pretty much every ancient city... everything was usually painted and plastered).
All of that construction and plastering required a LOT of limestone. Fortunately the Mayan realm sat atop vast reserves of it.
