Unbundling charger without standardizing the connectors would result in every manufacturer using their own proprietary bespoke charging connectors. Which is exactly what the situation was before usb was made mandatory.

CB actually have higher security standards than visa.
I once worked at a company doing payment card personalization (its the company who turn blank smart cards into finalized cards on behalf of banks. They print the customers names, emboss the account number, and program the chip and the magstrip)
Every year they had comprehensive security audits from Visa, Mastercard and Groupe Carte Bleue.
One guy there told me that they did the Groupe Carte Bleue audit first, because its the toughest. If they passed it they were sure to pass the others.
