Why do I want these things, as a user. App loading screens?
I love the web. I love hyperlinks, text and images. The web of connections that lead you to information. Everything in that list is detrimental to a good experience on the web.
I don't want push notifications, I barely enable them for native apps. And it bugs the hell out of me when every second website in desktop Safari prompts to send me push notifications. No. Why would I want this on mobile?
Same thing with the home screen. I love the fact that the address bar in my web browser is my history, my reminders, my bookmarks, my open tabs. I start typing what I want and I'm there. Finding native apps on my home screen is only just getting to the same place with Spotlight, why would I want to make the web worse by sticking icons for pages on my home screen?
And browser-guided dialogs to put more icons on my home screen? Seriously?
This author's post is a great argument against web apps on mobile.
You don't need all these extra features for a website. However, they are useful and needed for many web apps. Just because websites sometimes abuse these features doesn't make them bad.
A site should label itself as either a "plain site" or a "web app". "Sites" may only use a limited subset and amount of javascript (perhaps none?!). Browsers, search engines, and plugins can treat plain sites and web apps differently.
I too dislike the fact that web developers have the freedom to make design decisions with which I disagree.
