Exactly, and other than web pages (before this UX change), virtually every other well-defined piece of content that is likely to be shared had a prominent, distinct, easy-access share button on mobile (the separate copy to clipboard button added for URLs is not a common affordance; in most cases that functionality is one of many options accessed through the sharing function. OTOH, for URLs and certain other shared content, copying-and-paste is a particularly common sharing method, so promoting it to a first-class option further streamlines a common use case. ) This change actually better aligns the browser with every other way of interacting with shareable content on mobile rather than violating mobile UX expectations.
I click the url bar in Chrome, then the whole url shows up selected. Then I long-press to copy the url, but no! It auto-selects only a single word in the url and brings up the option to copy just that single word. Stupid.
Yes I know that I can click on the lock icon and then on the url, and that's what I usually end up doing, but that is also stupid.
Edit: sometimes it seems to bring the original url down in a dropdown with share/copy/edit buttons, but that doesn't seem to happen all the time. I haven't worked out why the dropdown often doesn't activate.
None of this UX design is perfect or totally settled, especially since it's only been 10 years since it's been mainstream.
