Does [Impact: unknown rules (versionbit 2) have been activated](https://bitcoin.stackexchange.com/a/107734/5406) answer your question?

No, actually.. I'm running the most recent release of Bitcoin Core and versionbit 28 does not seem new, as I've linked a thread referring to it from years back. 
Any idea what versionbit 28 refers to or where I can learn about these feature/soft fork signals in general?

Is versionbit 28 on testnet something that can be disregarded?

(Asked by: username_0 on 2023-11-08)

My testnet node is displaying a value in the `getblockchaininfo` warnings field related to versionbit 28, which I see referenced in various threads [going back years](https://github.com/bitcoin/bitcoin/issues/9080).

The angles I'm trying to address are:

* If I'm running the most recent version of core, is it still typical to see unknown rules once in a while? Should this situation be considered an unsupported softfork or something different?
* Where can I find out how to support newly activated rules i.e. what actions to take?
* Is this only some quirk because Bitcoin Classic forked on testnet ([see here](https://bitcointalk.org/index.php?topic=1471338.0))?
