Actually, LibreOffice is the perfect example, thank you. After OOo development went in a direction the community didn’t agree with, the Document Foundation was formed and the project was immediately forked. 13½ years later, the project is still updated every six months. It has every necessary feature and supports all formats. A browser would be similar; web standards don’t change that much. Wayland, by comparison, is currently a niche product for a niche product; it doesn’t need the same support, and so it doesn’t get it.
