No problem. No one can change a standard connection, when it is proprietary it is done through a different medium (ie lightning).
Yes, Netflix is one of the very few remaining services but that could change. These aren't native apps and providers have increasingly found that it doesn't make sense to have separate resources to power these server channels on old devices so those icons have disappeared as they drop support. Even things like wifi performance may degrade due to age, so just wanted to give you the heads up in case you need to upgrade sooner than you think. Have a good one.
