I'm on the complete opposite opinion. So many things are native apps but shouldn't be. Not to mention i have no desire to download a random app just to see if it does what i need it to ( consuming bandwidth and power in the process). A website is much more accessible, and can usually do the job.
If you think even basic websites/web-apps can replicate even 60% of their full functionality without JS, you are terribly mistaken. JS lets you do way more things than <form> lets you do.
