Hyperbole, but I’m excited for product team bug jams. No longer am I alone in my burden of being the deprioritised edge-case user without the power to fix bugs.
Once, I reported a bug for a feature that went missing when the screen was resized under 700px on desktop. The engineer then questioned how many users actually browse at such dimensions on desktop. It wasn’t many (looked at the data), but I was one of those users. So I managed to persuade the engineer to push a quick fix for me by providing the code myself.

Soon after, Chrome launched split screen. The floating action buttons used to be hidden and I confirmed it was a bug, not a feature.
Purely visual bugs, however, was a struggle to prioritise despite being a really simple fix.

Extremely niche Safari SVG zoom bug.
Additionally, designs almost always seem to be optimised for iPhones even though a good chunk of the world are Android users where the majority screen width is 360px. Not forgetting to mention the users who adjust the default font size.

Text gets cropped off.
The previous companies I’ve worked at designed for 390px wide screens. Designers might prepare an additional spec for handling translations using marqueed text or truncation, but this is often overlooked during development. A proper design system might be able to resolve many such issues yet design system adoption has been a struggle in the companies I’ve been at.
All in all, it’s great progress to be able to enable designers to resolve experience bugs more efficiently, and hopefully engineers would be more invested in design quality too.
