Google has announced they are dropping the info: command, primarily used to tell webmasters which URL Google considers the canonical URL in their index. At least that is what Google has been telling webmasters to use for this purpose for years. Now, you need to have verified access to the site to see such details in the URL Inspection tool.
John Mueller from Google wrote a blog post about what is a canonical URL. Then at the end, they drop this:
Weβve also changed URL Inspection tool so that it will display any Google-selected canonical for a URL, not just those for properties you manage in Search Console. With this change, weβre also retiring the info: command. This was an alternative way of discovering canonicals. It was relatively underused, and URL Inspection tool provides a more comprehensive solution to help publishers with URLs.
Yay and then - oh no!
URL Inspection Tool with Google Selected Canonical URL
So now the URL inspection tool added the ability to see what Google selected as the canonical URL. This is the URL selected by Google as the authoritative version of this page. Other versions can be served in search results, depending on factors such as the user's device type or language. This is not available in the live test, as Google selects a canonical URL only after a page is indexed.
Here is a screen shot:
Google Kills Info: Command
And the second part of the announcement is a by the way, we are dropping support for the info command. Google has been telling webmasters this is the best way to find the canonical URL of any URL in Google's index. Now, you can only know this information if you have verified Google Search Console access.
Google severely limited the info command a couple years ago and now it is just killing the whole thing off because it "was relatively underused."
The usage numbers were a pretty clear message, which we listened to. I realize there are sometimes rarely-used, highly-loved features (sniff...), but some of these take a lot of work / resources to run. (Also, if you ask "do you want X" the answer will be "Yes, but more", right?)

How long will it take to go away? It is unclear but John Mueller made it sound like soon:
Sometimes these roll-outs take a bit of time, usually it's not too long though.

John also wants to hear why SEOs want to keep the info command:
What would you do with knowing the canonical URL on a 3rd party site?

Glenn summed up the main reasons well:
The points about viewing the canonical for a non-verified site would be 1) if you can't get access to a client site, 2) if a client hasn't set up GSC yet for the site, subdomain, etc. or 3) to analyze the competition. There's a lot of 3 btw. :)

John says Google didn't kill it off because they hate SEOs:
SEOs are an important part of the web ecosystem, certainly not competition for a search engine.

SEOs will adapt, they always do.
