Of course. But the "old" version I've installed is still very recent, July 2023, and I'd assume there are a ton of devices out there still running that build and even older builds with no way to update. They could cut old versions off, but they would be cutting off a lot of users.
When I did this in 2016 for eBay and Google Inbox I got a year out of each.
For this Twitter app, I'll enjoy it whilst it lasts. I'm a glass half full kind guy.
