That said, bigger news sites were probably whitelisted...it seems like the whitelist could be done algorithmically...but the number of new authoritative news sites, in theory, changes so slowly, that there's probably not really a need to do that.

"The URL for each article must contain a unique number consisting of at least three digits. For example, we can't crawl an article with this URL: http://www.google.com/news/article23.html. We can, however, crawl an article with this URL: http://www.google.com/news/article234.html. "

That's because your excerpt from Google News' guidelines left off a very important addendum: "Please note that this rule is waived with News sitemaps."
Thought these days a news sitemap suffices.
I would personally still add the 3+ digit unique number to the permalinks and eventually if necessary remove it once rankings improve overall on Google News.
Some Back Story
==================
I consulted for a Movie News and Review website for about 6 years. We had news sitemaps and would show up on Google News once in a while, but one of the small yet significant changes that we made that increased ranking on Google News was when we implemented adding a unique number to urls.
That was implemented back around 2009-2010.
We stopped using that unique numbers in the URL around 2013, mostly because the numbers were becoming pretty darn big. We noticed a small downtrend in Google News traffic which stabilized in a couple of months.
For anyone using Wordpress unique numbers can be added using a permalink structure such as:
/%postname%-%post_id%/
If you do decide to use it don't forget to setup 301 redirects.also it makes the URL longer, less user friendly and you have to deal with an URL migration that you might have to revert at some point (i.e.: the example you mentioned)
additionally: as it is mentioned that the 3 digit requirement is "waived" with a google news sitemap it is a strong indicator that this is a crawling, not a ranking directive.
my 2 cents: don't do it, as it would be a clear violation of the golden URL rule a.k.a. "Don't overdo the f###### URLs!"
"Please note that this rule is waived with News sitemaps."
so basically the >= three digits rule doesn't apply any more (for years now), as a matter of fact i don't know why google still has in in there as it always leads to a lot of confusions.
i once consulted a big newspaper which were in an ongoing project to change their URLs just because one of their (middle)managers has read this spec...
