UNet deprecation date

I read through the FAQs regarding UNet deprecation, but I'm afraid that I'm still not understanding. https://forum.unity.com/threads/unet-deprecation-and-removal-plan-2021-update-and-faq.1137190/


I have an app that uses HLAPI to have phones use NetworkDiscovery. While on the same network, they meet up in a lobby and connect from there. If I release this app to my client in late 2021, will the networking feature still work until 2022? I know that it will still be in the Unity editor. But will the feature still work? And for how long?

I'm planning on migrating to Mirror in the future, but I just want to see how much time I have left before I need to make that move. Adapting my current project to Mirror has proven to be difficult.
