Subscription management would be nice, but it’s a bit more complicated than simply blocking transactions; just because a tx doesn’t go through doesn’t mean you opted not to continue with the service, it just means the service provider was unable to collect on your payment. For new tech companies like Netflix, a lapsed subscription goes away easily since it’s prorated so they just stop providing you service, but many companies take the hostile route and send any lapsed subscriptions to collections without blocking access to their services.
