Good news! This will enable a bunch of future in-buffer graphics features -- things like Headless/Playwright Chromium using Emacs as a display server or faster PDF viewers. Org-babel should be able to make use of this too for faster data plotting. I can only imagine the kinds of snazzy Emacs graphical UI interfaces this will enable, beyond what is being currently done using SVG hacks for rendering.
