Is it good or bad to Link Preload font/fontawesome files?

XenForo 2.1 by default preload this files:

Code:

<link rel="preload" href="/styles/fonts/fa/fa-regular-400.woff2?_v=5.12.0" as="font" type="font/woff2" crossorigin="anonymous" />
<link rel="preload" href="/styles/fonts/fa/fa-solid-900.woff2?_v=5.12.0" as="font" type="font/woff2" crossorigin="anonymous" />
<link rel="preload" href="/styles/fonts/fa/fa-brands-400.woff2?_v=5.12.0" as="font" type="font/woff2" crossorigin="anonymous" />

I removed it on my own site and Start to Render decreased which I think is good.
Eva however preload it on this Forum, that's why I'm confuse what's the best setup.
