I haven't been involved in the home automation industry for a while, but if there were any integrations that used this API from DIY or commercial platforms like Homeseer, Control4, Crestron, AMX, or dozens of others, those will no longer work.

There are lots of mostly invisible companies selling high-end automation that don't need to advertise so you'll never have heard of them. It's not just hobbyists that build this stuff.
