We agree, site speed is a huge issue. Neto has just announced an improvement to site speed by allowing webP images to be used. However it turns out only product images can be uploaded in the webP format. What's needed to improve loading front-end pages is allowing webP image format for Advertising Campaigns. This is where it really counts - it affects load time of the home and category pages. Anything else they can do to improve site speed would help.
