We added this unstable feature a few years ago, as a way to opt out of context updates, but it didn't prove useful in practice. We have other proposals for how to address the same problem, like context selectors. Since it was prefixed with `unstable_`, we should be able to remove it without consequence. The hook API already warned if you used it. Even if someone is using it somewhere, it's meant to be an optimization only, so if they are using the API properly, it should not have any semantic impact.

Hey there! The use-context-selection used the I completely understand the feature was marked as unstable and thereby there were risk for it to be removed. This comment is just to ask/check if there is a 1:1 replacement I could use/explore to support a similar behavior and integrate in the mentioned library (?) Otherwise, I think I'll update the library Readme to make it clear this won't work for React >= 18, and probably suggest opting for https://github.com/dai-shi/use-context-selector instead Thanks in advance for any help! |
Sorry, there is no 1:1 replacement. There's been initial work on #20646, but it is currently paused. |
