In this link, it is explained why a client sends probes to a hidden network: link
And here it states that clients will send probes for any network to save battery: link

So does it make a difference from a privacy perspective if clients are broadcasting the SSID anyway?

Because hiding it would help against wardrivers and google pinning the SSID to a location.

    Hidden SSID is more of an UX feature than a security one. It's good to be able to hide dozens of internal/management SSIDs in order to present a clean UI to your customers with only the networks that are relevant to them. Mar 23, 2017 at 10:00

First, we agree that hiding the SSID is not a security feature. But it can be handy sometimes because the attacker needs at least one connected client to a hidden network to send de-auth and get the SSID.

Most important, hiding the SSID might affect client's privacy. Because the client is broadcasting a trusted network SSID, so a rogue AP can be set by an attacker, and then he might be able to set mitm. "only if the network is set to open auth"
