@acdlite, @rickhanlonii, @gnoff, @eps1lon, could one of you review this please?
I'd like us to merge this PR as soon as possible, invite a few early adopters to test it even more before we market it more broadly. Thank you.

We do not recommend removing useMemo and use callback while the compiler is still experimental. The compiler may skip components for various reasons (violations of React’s rules, as-yet-unsupported syntax, etc) and a blanket codemod to remove all manual memoization could cause problems.

We strongly recommend waiting until the compiler is stable. We plan to provide a script that will only remove manual memoization where the compiler is running, skipping components/hooks where the compiler would bail out.

Let’s remove the “remove memoization” code of from the PR - thanks!

[alexbit-codemod]

noted. we will remove it soon. thanks for flagging.

@rickhanlonii do you prefer if this link goes to our github, upgrade recipe, all react 19 codemods in registry, or somewhere else?

[rickhanlonii]

I don't have a preference, that was what the codemod team added in a previous commit on this PR

Thanks!
