Google Home Routines - Nest Secure triggering routine

Hi everyone,

I have a few things connected to Google Home and I'm trying to do some automation here and there. One idea I had was to have my Nest Detect on the window trigger my thermostat to decrease the temperature when I open the window for some fresh air.

I have a Honeywell thermostat that is connected and I have 3 routines that change the temperature based on time. I also migrated my Nest account to Google so that I can use the Nest Secure as assistant. I thought first using IFTTT but I had to realize that I missed the boat by a few months. Then I found this article:

It talks about these fancy new Home Routines where Nest devices would be able to trigger actions. Is there any ETA on this? All I can find are various articles from the same time parroting the same message as in the official blog. I'd love to have such routines but it doesn't seem like it would have been realized at all.
