Exposure Notifications was designed to be deprecated, though? It was a pandemic thing.
We have however wound down most of the protective measures. Germany has retired the official bluetooth contact tracing app earlier this year. I wouldn't be surprised if Google retires theirs this year or the next.
It's just as dangerous (well, it's probably not, due to less lethal variants winning over more lethal ones), but that measure is not what makes it no longer a pandemic.
Per the WHO[1] and the CDC[2] COVID is still a pandemic.

Google does not have their own app. Exposure Notifications is the cross-vendor low-level API which apps like Germany's is (...was) using.
