The goal of this check is to discourage people from preloading assets using plain HTML in cases when it is possible to use Liquid filters instead.
It is sometimes the case that <link rel="preload" ...> is positioned late in the <head>, preventing the browser from discovering it early. In addition, this manual approach is not automatically converted to Link header so Shopify is not able to forward it to Early Hints response. These issues are not present when using Liquid filters mentioned above.
