The difference is that LibreOffice, Firefox, and GNOME are really really technically complicated.

Document file formats are a fucking nightmare, especially the Microsoft ones, and needing perfect compatibility with them spanning a generation is hell on earth.

Firefox is a similar scenario but for the web and decades of "it works on the dominant browser but the dominant browser refuses to follow the spec".

And GNOME is a matter of varying levels of direct hardware support/integration and app compatibility across basically the entire personal desktop computer and laptop eras.

Each of those has a compatibility scope that's absolutely massive.

Comparatively Tangled is a greenfield project with no compatibility requirements other than "support git" and "don't break compatibility with itself".
