The lack of pressure leads to absurd file sizes for silly things.
A few weeks ago, I needed a vector company logo, so I asked our graphics team for one. The file they sent me was 6MB. While working with it, I noticed it was actually quite clean, so I exported it as an SVG and it came out to 2KB. 1/3000th the size for the exact same graphic.
I opened their file up in a text editor and found font configs for specific printer models (in a graphic with only filled curves), conditional logic, multiple thumbnails, and other junk.
