Patch

View in context: <a href="https://bugs.webkit.org/attachment.cgi?id=299919&amp;action=review">https://bugs.webkit.org/attachment.cgi?id=299919&amp;action=review</a>

I think the current approach is fine. CachedResource is supposed to encapsulate these things anyway.
We do have a lot of indications and weird class hierarchy in the loading code through.
Instead of adding a new class, we should consider refactoring them into a more coherent set.

<span class="quote">&gt; Source/WebCore/dom/Document.cpp:5047
&gt; +    // Parser should have picked up all speculative preloads by now
&gt; +    m_cachedResourceLoader-&gt;clearPreloads(CachedResourceLoader::ClearPreloadsMode::ClearSpeculativePreloads);</span >

We never call this function anywhere else e.g. for link element's preload.
Can't we just rename this function to clearSpeculativePreloads instead?</pre>
