Do i need to remove this wp-block-library-css (Gutenberg CSS)?

Question

I just want some clarification and advice regarding this tag in WordPress.

This tag is showing in my WordPress head even I'm not using Gutenberg.

link rel="stylesheet" id="wp-block-library-css"

Is this necessary or required? Do I need to remove this to improve page speed?
Is there any effect if I remove this tag?

Please enlighten me.

Thank you

I use to remove this stylesheet on websites which are not using Gutenberg.

I don't think there is other effect than removing this stylesheet, you can do it safely.

To go a bit further, you can remove it only for some post types like

function remove_wp_block_library_css() {
  if( !is_singular('post') ) {
    wp_dequeue_style( 'wp-block-library' );
  }
}
add_action( 'wp_enqueue_scripts', 'remove_wp_block_library_css' );
