## Code

```php
// Post type => block names allowed in its editor.
$wpide_allowed_blocks_by_type = array(
    'testimonial' => array( 'core/paragraph', 'core/quote', 'core/image' ),
);

add_filter( 'allowed_block_types_all', function ( $allowed, $context ) use ( $wpide_allowed_blocks_by_type ) {
    if ( empty( $context->post ) || ! isset( $wpide_allowed_blocks_by_type[ $context->post->post_type ] ) ) {
        return $allowed;
    }

    return $wpide_allowed_blocks_by_type[ $context->post->post_type ];
}, 10, 2 );
```

## Notes

Post types that are not listed keep every block. Blocks already in a post keep working.
