Most "applications" I visit in my browser have no business being an application. The "clear search history" button in my start menu has no business loading a React environment with three redirects either.

Some web applications need a boatload of frontend stuff to make them usable, but I rarely encounter websites that warrant such overkill. A payslip/email subscription/car rental website with a profile page and maybe three forms I can possibly need to submit doesn't need to be a fully interactive application with loading bars and offline support, leave that stuff for the websites I visit more than once a month.

At this point React/Vue/Svelte devs are probably cheaper to hire than basic JS devs, but technology wise the amount of Javascript my browser needs to load for the most basic interactions is mind-boggling. More than the "this meeting could've been an email" meetings, I run into "this web application could've been a POST request" web pages.
