Clicking the link shouldn't be enough to consider a target to have fallen to fishing. Sometimes, if a get a fishy email, I open it in a private tab within a browser I don't use, or even within a throwaway VM (if I feel something is REALLY strange).

Clicking a link is all it takes to download malicious code and send stuff to an attacker. Clicking a link is enough to consider a target to have failed.
It shouldn't be though. If your threat vector includes teams with something like Chrome 0day, you've got bigger problems than employees clicking links. Malicious email in the wild is either a link to a phishing page, or a link to a page offering an executable.

If I paste a URL urlscan.io and have a look at it, I can assess better whether it might be safe. Being told "url got hit, you compromised us" is really silly in my view.

^ this.

Of course "click to fail" is silly. And, in some experimentations I did in the past, it's usually easy, in a large organization, to forge a 100% legit url (like somefileserver.organization.com/some_url_that_can_be_easily_edited_by_anonymous_users) and a 100% legit sender (because of some open relay that passes DKIM and/or SPF). So you just need an access to a minimal-security internal network (easily obtainable through spearphishing or malicious employees) to perform a good phish.

The obvious attack vector is to insert some JS in the webpage that performs a redirection to an external server holding malicious data. But the user would fail IFF they entered the data there, not just by clicking.

This is, uh, obviously not true.

Feel free to provide me with a link that will "send stuff to an attacker" with only me clicking it and no other action.

No way, that'd be a 0-day and you wouldn't want to burn one doing phishing.
The URLs include some unique identifier that’s traceable to you. As far as my company is concerned, merely clicking it is grounds for security training.

Edit: I guess the argument is any page could contain an RCE.

Wow. If a single click is enough for a RCE, you've got bigger problems, IMHO. Basically, each and every website can hack into your infrastructure.

I'm not sure whether there are policy recommendations about phishing, but as far as I'm concerned a target would have failed if they entered private data somewhere, or opened downloaded documents or executables.
