Libre Office is already bloated to the point of being unusable imo. If some features are not available in a given context, they just should not be shown, instead of trying to show off how it's superior.
If the UX isn't done well I agree. However there a great opportunity for pushing for compatibility and a more portable document format in a less annoying way than gimp does for xcf.
i think the bloatedness has improved in the last year. start-up times and responsiveness are much better
