Caveats
The protocol is early-stage and its specification is not yet published. The article cites no survey data and mixes reporting with editorial opinion; it flags that data errors could multiply and platforms could gain control at customers’ expense.
Our read
A shared way to say “this agent acts for this customer, with these rights” would help. Wait for the actual specification before building to it.
