They did stop using Laminated Safety glass on car side and rear windows, they are all Tempered now. But car windshields are still Laminated Safety, because you want to stop the rock, not let the windshield crrumble and let it through.
And it's still readily available as flat plate glass for older trucks and buses, and the odd sizes on motorhomes.
They don't try to stock factory-cut glass for one-offs like a 1970 Flxible or a 1964 Crown Coach, your local glass company orders a full sheet of Laminated, makes a template, and cuts it out to order. Sand the edges, cut a new length of grommet, and stick it in the hole.
