For those with XPro+, no images are created by the decorations.
That said, the resulting index file is almost 2MB, rendering around 11,000 blobs.
Without SVGs, the images sizes hit 8MB.

For those without, there is a Scatter Brush, Xmas Deco, that you can use sparingly.

As the Brush is a Line, to get no images, you need to Convert Line to Shape and Ungroup.
I would then Soft-Group to keep things together.
