What problem does this feature solve?

Option 'target=ES3' is deprecated and will stop functioning in TypeScript 5.5. Specify compilerOption '"ignoreDeprecations": "5.0"' to silence this error

What does the proposed API look like?

Per microsoft/TypeScript#51909:

What should I use instead?

target: ES3

ES3 runtimes are nearly 100% extinct, so we're removing support for this as an emit target.

Fix: Use target: ES5 as the next-closest thing along with a linter to detect any potentially-problematic ES3 constructs, or use target: ESNext and use a different downleveling emitter.
