Adoption — overview
The market signal. Below: where PDTF is in production today, what counts as "adoption" (it's a spectrum, from a single overlay used in a UI to full certified provider status), and the public evidence trail.

The adoption spectrum
"Using PDTF" can mean very different things at different levels of integration. The DPMSG draft framework defines five levels:

Five levels of PDTF integration. Most current adoption is at levels 1–3; the Sandbox is testing 4–5.
