Mobile Push Notifications Question

Description

We currently run a 1.3.1 versions server and i am planning to upgrade this server to 3.3.0 (or whatever the latest version is at that time).
There are several improvements but the notifications are the ones that interest me most .
I have noticed today that by registering the workspace an email is being sent out that says:

“By registering your workspace with Rocket.Chat Cloud, you will be able to use:
Mobile push notification gateway
• Livechat omnichannel proxy
• OAuth proxy for social network
• Apps Marketplace”

Does that mean i wont have access to the push gateway anymore after upgrade unless i register my workspace ? Or is that something else? I have been using version 1.3.1 with notifications normally without any kind of registration.
