I don't want this feature enabled for me as a customer. Most of the time I go on my bank's website and generate online credit card numbers with a ceiling amount. Those come with a fixed expiry date (usually very soon, one month after card is created). I use this to be sure that I don't get trapped into a recurrent payment that I would have missed in the fine print.
How can I make sure that an online shop will not be able to draw money off my card after the expiry date? If I understood the technical magic here, that would help.
