But how would that work? If I get warping on the A1 Mini already sometimes, I can't imagine how a bed this large without enclosure could perform without warping.

A lot of warping comes down to part design, build plate cleanliness, and build plate material.

Hmm. Oftentimes when I try to print something that covers the whole or most of the printing area in one direction, for example boxes of varying sizes, I have the corners lifting off more or less, or the build plate lifting off instead.  (And I always make sure the plates are clean, for something large I often use the Supertack plate and / or large brims, and I also design my stuff with round corners). I accepted it as part of the material properties and process with a not enclosed printer, but since some people are writing that there shouldn't be warping with the A1 Mini I would be thankful for further tips.

Add some rabbit ear brims and adjust cooling for first few layers.

Build plate matters some. I get less on my biqu plates, but it still happens.

I think most of it is build plate cleanliness though
