Author here. At the time, Angular relied a lot on the AOT compiler and tree shaking to keep bundle sizes down. No idea if this is still the case.
If we built the app with the stable branch the bundle size was orders of magnitude smaller: less than 200kb. Still a bit of a chonker, but more reasonable than the ridiculousness the experimental SSR branch spat out.
