`importHelpers` incorrectly requires `tslib` for native `#private` class members at every dated `target` (ES2022–ES2025), even though no helper is ever emitted

Important limitations

• This may be one public report, not widespread demand.
• Current independent report count: 1.
• This is currently a single independent report. It has not passed clustering or human review as a verified signal.
• No market size, willingness to pay, competition, or trend claims are inferred here.

Workflow

- Reproduces on every TypeScript version from **4.3.5** (when native `#private` fields and the `ES2022` target were introduced) through the current **7.0.2** and the **7.1.0-dev** nightly — i.e.

Desired outcome

`tsc` should not require `tslib` to be resolvable for constructs that are natively supported at the configured `target` and that the emitter never actually references, the same way it doesn't for e.g.

What would upgrade this

• Additional independent reports from distinct communities or authors.
• Human clustering into a review signal, then explicit publication approval.
• Counter-evidence review and durable original-source verification.
