Yes you are correct, this would be very useful and I have thought about this.
The first user of such a plugin would be myself. I want to use it to sell subscription to the dashed-slug products and service.
I do not think that the best approach would be to integrate it with WooCommerce though. This will either be a payment gateway for an established membership plugin, or an extension to the wallets plugin that will control user roles according to some recurring payments scheme.
In any case it will have to be done after I work on the exchange. The exchange is the most requested extension by far. Therefore I am unable to give you an estimate on when I would start work on subscriptions.
Thank you for sharing this.
kind regards
