Yes, we found our customers like to shrink our webapp down to half the screen, multitask, etc. Assuming full width even if their screen dimensions were large was a bad idea.

I often scale my browser window to 30% of the screen's width(it's a large screen).

Webapps and responsive webpages often like to either switch to a layout made for smartphones which looks really weird and makes some links and options inaccessible, or it just breaks in some ugly way. I've seen websites literally becoming unscrollable when the browser window got too narrow, websites where writing in a text field would gradually shift the site out of the visible area, forums that would hide away the "reply" button in narrow windows, instead showing the "report" button in the same location(facepalm).

Web developers should stop assuming their website is the center of my world and attention.

They really should just focus on the content, and not obsess so much about how each and every pixel might look on my various browsers, and stop trying to make assumptions and guess about how I might prefer things to look based on silly things like browser width and user-agent string.

Yes, I almost never have my browser fullscreen (only when the page layout forces me to), and instead use a roughly 1:1 aspect ratio in the middle of the screen, so that text lines aren’t too wide and text starts not too far on the left. That’s with a 27" 16:10 screen.
