Most of the rss readers I know allow that. What OP built there is something that stays in sync with your subscriptions, so when you add or remove one it is automatically added or removed from you reader and do not need manual intervention

If you have a feed reader system there is no need to subscribe in the first place. You’ve obviated that system.

Why though? You already have the feed urls. A list of urls is the same a subscribing to channels essentially. Both do the job of letting you know a new video is released.
