Spackling Q2 / 2 coats of paint - sufficient?

We have been offered the following for our single-family house – is this quality sufficient or should we pay the extra for Q3? Or is it reasonably okay if Q2 is painted twice?

"All interior wall surfaces of the brick masonry receive a felted lime gypsum plaster. The walls in the wet rooms receive a lime cement plaster. Corner protection strips at external and reveal corners. Movement profiles at movement joints. Interior plaster surface Q2. The ceilings in the living area are fully and rigidly plastered. The wall and ceiling surfaces receive a 2-coat opaque dispersion paint finish in white."

I would rather invest in silicate paint instead of more smoothing. But everyone has their priorities. The additional cost for other paint can usually be clarified directly with the craftsman.

The trend towards baby-bottom smooth walls is completely incomprehensible to me...

I agree. I even find fine grain already in the plaster. If the plaster is well done at Q2, you can paint without any problems.

We will also receive Q2 from the GU.

Our painter said that with a little rework you can paint directly on it.

He still offered Q3 as an option. The additional cost is (for 600 sqm wall and ceiling surface) just under 3k net.
Then paint with silicate paint.

Oh cool, thank you very much for your helpful answers! Then I am completely reassured regarding Q2. I also think that the walls don't have to be perfectly smooth.

Regarding silicate paint, I still need to do some research - I don't know anything about it yet... so you all say silicate paint is better?

As far as I understand, it depends on the plaster.

Lime-cement plaster is diffusion-open and forms a bond with the silicate paint – "silicification." Silicate paint is fungicidal by nature due to its high pH level.

Dispersion paint is the "normal" paint, as I know it from the hardware store. It does not bond with the plaster but rather covers it. Fungicides are then added as needed.

And there are hybrid forms.
