Sorry for the delayed response.
After some deliberation, we decided to stick to the page limits in the CfP. For long papers, that is a maximum length of 16 pages with 4 pages of references.
For short papers, 8 pages with 2 pages of references.
We’ve reconsidered our earlier decision. We all benefit from some additional pages to better interact with the reviews:
Long papers may use two additional pages, and short papers may use one.
