The scheme is an essential part of the URL. Copying an URL from a browser's location bar used to be a reliable way of sharing links, but this change introduces a greater potential for errors (there's no reason to assume an https resource is available via http, for example).
Copy-pasting includes the scheme (mostly, there's a couple bugs at the moment). Better to read up on the issue before commenting about how it's supposedly broken.
I didn't say it was broken, but that the change increases the possibility of errors. Look at the other links provided in this thread to see why this is so. I stand by my statement, which I made after reading up on the issue.
Not consistently. This is a critical part of URLs. Not displaying it is like not displaying zip codes in US addresses (I recently lived at an address that differed from a nearby address in zip code only. We were constantly returning misdirected mail to each other.).
It (https) is displayed consistently in Chrome's address bar though. I agree that the scheme is a critical part of a url. The question is whether a real url must always be shown in the address bar.
