Suspending the ceiling without counter battens?

Dear community,

I need your help again:
In my new house, I hired a drywaller to hang the ceiling on the ground floor because we want LED spots there. I told him that I want to lose as little height as possible and therefore the ceiling should only be recessed as much as necessary.
Today, I looked at the first results and noticed that the craftsman omitted a counter battens and only installed the base battens in the direct hangers.
Now I am wondering whether this is really such a good idea and correct? I have uploaded a photo.

I look forward to your advice, thank you very much!

Fits perfectly. Is state of the art.

The craftsman is doing exactly what you want. A construction "expert" might have doubts, but I, for example, have done it differently myself. So all is well.

Of course, you can do it that way. That is what the direct hangers are for. The only important thing is that you lay the cables for the spots before installing the drywall panels.

And pay attention to the installation height of the LED spots. There are also relatively deep LED spots.
