Why the WooCommerce 3.6 first included an option to either enable or disable usage tracking and then suddenly 3.6.1 and it’s no more there?

I have upgraded to WooCommerce 3.6.1 a day ago. I have found that the Usage Tracking feature, which was earlier released with 3.6, has been removed (ref: https://www.cloudways.com/blog/woocommerce-3-6-features/).
