That means a project which enables following features at the same time will be unusable under TS 5.5:

1. enable both emitDecoratorMetadata and experimentalDecorators in tsconfig.
2. use declare keyword for class properties.
3. verbatimModuleSyntax is false.

Some of my projects cannot upgrade to TS 5.5 too.

Using https://www.npmjs.com/package/every-ts, this bisects to #58366. @weswigham

It looks like this bit was added:

        if (location.flags & NodeFlags.Ambient) {
            return; // References within types and declaration files are never going to contribute to retaining a JS import
        }

Which explicitly skips marking references for declare.
