Could we have other clients that might need this? Or is this truly just a case of our test infrastructure needing this turned on.

How do client applications that will need content filtering signal this fact (e.g., Safari) opt into this feature?

I don't believe other clients need this. The API test is testing whether the network extension framework is loaded in the WebContent process, and the patch in r253351 avoids loading the framework unless it is needed, introducing the failure. The test fix swizzles [NEFilterSource filterRequired] in the UI process, which will cause the framework to be loaded in the WebContent process.

Thanks for reviewing!
