Is Opting out of Google Play App Signing permanent?

Question

I've only seen guidelines and articles about how the Google App signing works, how it benefits you and that it is permanent once you've opt in. But I can't find any proof that if you opt out once, will you be able to use it in the future?

Example: I'm trying to release an app, but I don't want to opt-in right now. In the future, I might. If I do change my mind, will I be able to opt-in again?

Answer 1

Yes, you can opt-in later. And once you do opt-in, it's permanent. I finally just opted-out because I wasn't sure if I'm willing to commit to this new and permanent idea. So I got this pop-up message from Google Play store which answers my question. I hope this helps everyone out.
