🕗 Version & Regression Information

• This changed between versions N/A and 5.7.0-beta
• This changed in commit or PR Rewrite relative import extensions with flag #59767
• This is the behavior in every version I tried, and I reviewed the FAQ for entries about these config flags and JSON more generally (nothing found)
• I was unable to test this on prior versions because rewriteRelativeImportExtensions did not exist

💻 Code

// package.json
{
  "type": "module"
}

// tsconfig.json
{
  "compilerOptions": {
    "module": "NodeNext",
    "rewriteRelativeImportExtensions": true,
    "resolveJsonModule": true,
  }
}

// example.json
{ "example": true }

// example.ts
import * as example from "./example.json" assert { type: "json" }
                         ^^^^^^^^^^^^^^^^
// This relative import path is unsafe to rewrite because it looks
// like a file name, but actually resolves to "./example.json". ts(2876)

🙁 Actual behavior

import * as example from "./example.json" assert { type: "json" }
                         ^^^^^^^^^^^^^^^^
// This relative import path is unsafe to rewrite because it looks
// like a file name, but actually resolves to "./example.json". ts(2876)

🙂 Expected behavior

No error

Additional information about the issue

The documentation says:

/* Rewrite '.ts', '.tsx', '.mts', and '.cts' file extensions in relative import paths to their JavaScript equivalent in output files. */

I wouldn't expect this to apply any sort of change to a .json file.
