    This hook is poorly named: when returning `true` with this hook; many 3rd-party blocks’ assets (JS and CSS) will only load when those blocks are being used on a page; slightly speeding up your website.

    To use:
    add_filter( 'should_load_separate_core_block_assets', '__return_true' ); it only needs to be added once for each instance of WordPress you are working with; you do not need to add for each block or plugin that you wish to conditionally load.
