Will be added to the pending list.

@Rel1cx Let's just track them right here then. I will start porting those rules when I get time.

jsx/enforce-jsx-key has been implemented by the three rules

• jsx/no-missing-key
• jsx/no-duplicate-key
• jsx/no-array-index-key Except "before-spread", the implementation of these three rules can detect more problems than the original rules. If necessary, we can also add a jsx/ensure-key-before-spread

[Rel1cx]

Some differences between eslint-plugin-react and @eslint-react regarding jsx-key rules

[Rel1cx]

And no-object-type-as-default-prop already implemented and covered by no-unstable-default-props

[hyoban]

naming-convention/filename-extension already implemented by naming-convention/filename-extension

[Rel1cx]

Since many rules has been changed, we track the migration status in #85.
