Sandly, Automattic / WooComm is responsible for such thing.

For example, the product gallery is such all images - thumbs and main slides - load on page load. If you don't click any thumbs - and had 10 total images - 9 would have loaded for naught.

But there are BE + FE ways to fix that :)

Also, WooComm recently introduced HPOS that moved order meta into its own table. Smart! But there is still order data captured for every order (e.g., customer order IP, etc).that's in the meta table. Why those we're moved to the new table IDK.

The real issue is that customers without knowledge are asking explicitly for wordpress instead letting us techs give the best advice.

Most techs give terrible advice.

On the other hand, most techs are bias. That is, the tool they know is always the best solution, whether that's true to not.

Yeah, perhaps there are times when WP isn't the ideal choice from a pure technology POV, but there's more to it than that. For example, most (solo) devs complete dismiss the "getting hit by a bus" test. Sorry, but no one should accept advice from anyone who dismisses that test.

wordpress is being marketed, deployed and then abandoned without maintenance by seo experts and designers, not techs nor devs.
