This isn't an issue if you're not using the ISP equipment, or put the ISP equipment into a bridge modem mode.

For instance, BT in the UK do the same reporting over TR-069 if you use their home hub - however - if you connect a different VDSL modem/router you can disable TR-069, and if you use a dedicated VDSL modem in bridged mode and a wireless router behind that there's no TR-069 to worry about in the first place.

Or if you just use the provided router, either in bridge mode or in regular mode, the only device it will ever see and report on is your own router, which is hardly a critical leak.
