The sad reality on most WordPress addon's, themes, etc, is that very few consistently update anything. Many will say "new" design every week or so, and I have never seen it done. Exclusive Addons has been talking about adding on to its Template library for a long time, it looks like it was stuck in 2010. It is unusable. Tons of code errors will pop up even though browsers have greatly reduced the number of errors that are shown via various filters and levels of importance. It is as bloated as ever & literally I have not seen 1 good update. There is no support so don't even try. Unfortunately, this is true for many of the add-ons such as Unlimited Elementor, ElementKit, Element Pack, Plus Addons etc. But Exclusive Addons is by far the worst kept & provides outdated solutions, does not have any new animation or features and as I mentioned pre-designed blocks are extremely lacking.

Some themes have decent template libraries like ThemeRex but unfortunately they're arent stand alone.
