Now, that's not as transparent to grok or as high resolution as something like the date and title path schema that's become popular, but it's still something that some users will recognize and possibly even know how to get some utility out of -- if nothing else, by copying the URL and pasting it somewhere for sharing or use or storage.
And that's the worst case scenario for URL utility. If we get into a recognizable scheme like the date-title path, there's a lot more apparent information and it can often be transparent how changing the URL can be an interface.
We've had an interface that allows users who don't grok URLs to ignore them OR learn by observation and experimentation how they work -- and allows users who are already there to easily note and access them for two decades.
This trend towards leaving them out doesn't allow that progression or utility.
