Agreed, but not even a battle-hardened production compiler requires a particle accelerator or an optical fibre cable to the Webb space telescope. Similarly, a shopping site or text-based social media
does not require a soup of web frameworks. It just doesn't - it's not a solution commensurate with the scale of the problem. Complexity is expense, and this doesn't remove complexity, it introduces it, reams of it, and totally needlessly.
No one has ever sat in front of a shopping site and thought - 'you know what this needs? A dozen extra mb of JavaScript that introduce no actual new customer-facing features, but that put a noticeable delay in every interaction, break the user's scrollbars and screen readers, and dramatically complicate maintenance.'
