Arduino Editor no install

I find it interesting that one of the first blog post from Arduino about the new editor stated;

"First of all you will be able to write code and upload sketches to any Arduino board directly from the browser with the Arduino Web Editor (IDE), without having to install anything"

Yet we have to install a plugin.
Is there a way to use the new editor without it. I'm using a PC where I'm not allowed to install anything. Or will there be a Chrome browser extension because I'm able to install those?
I find it interesting that only requires a chrome extension.

Hi @jackjameshoward,
at the moment you need the plugin to be installed to perform upload on boards.
Thanks for your feedback
