WebBundles can't hide content any more than a regular server can, and blockers can block individual resources from a bundle like they can individual URLs from a server.

but you have to download the whole bundle so you don't get the benefits of blocking at the loading stage, which is quite impactful.

remember that chrome / chromium hamstrung the ability to block at the loading stage; only firefox, ff derivatives and hacked up chromium derivatives can still block prior to loading with complex rules.
