Sorry, I don't get it. If you have client side rendering, you need a template for every thing you want to replace, at whatever level you choose (from full page to single element). If you do htmx, you do the same - provide a template for each replaceable part (from full page to single element). In each case, it's your choice how granular you want the updates to be - it can be one per action, or just rerendering the whole page. Why do you think the client side requires fewer partials, if you use the same scope of data changes?
