The relevant text is:

This is unambiguously not just about Finder. It says all apps must match how Finder reports file sizes. The HIG is clear and precise in this regard, and doesn’t include any exceptions or special cases for developer-facing apps.

Which examples are you thinking of? Note that when we looked into this (https://goo.gle/devtools-si), Firefox DevTools were on board with making the change. We’ve already made the change in Chrome DevTools.
