JavaScript API client, HideCommunity - disabled?

Someone was asking about it in support, so I was curious to try it. The Rust code has HideCommunity, I even tried to bypass the JavaScript client and do a direct API call.

Does anyone see the function call to send a HideCommunity object?

Where it might be disabled in the Rust code? I know it goes all the way into the database and is on SELECT statements.
