Google's announcement about this and several new attributes, was on Sept 10, 2019, roughly six months ago, suggesting that rel="nofollow" would, at Google's discretion, be treated as a hint after March 1, 2020. Here's the WebmasterWorld thread from September...
Google adds new options to NOFOLLOW Sept 10, 2019 https://www.webmasterworld.com/google/4963657.htm [webmasterworld.com]
And here's the official Googleblog article, by Danny Sullivan and Gary Illyes, covering how Google had treated "nofollow" since its arguably necessary introduction some fifteen years ago, to fight comment spam.
Evolving “nofollow” – new ways to identify the nature of links by Danny Sullivan and Gary Illyes

I suggest re-reading both the Googleblog article and the WebmasterWorld thread.
Essentially, as I saw it then, and still do, Google wasn't
requiring anything additional from the webmaster. For those who wished to play by Google's rules and be indexed by Google, flagging ads and sponsored links was still required, but Google, in deference to an installed user base, was not asking for any changes... rel="nofollow" would still suffice.
For those who wish to use new attributes which it is expected might eventually help the algo become more granular, Google offered several new options. As summarized in the last paragraph of the Googleblog article...
All the link attributes, sponsored, ugc and nofollow, now work today as hints for us to incorporate for ranking purposes. For crawling and indexing purposes, nofollow will become a hint as of March 1, 2020. Those depending on nofollow solely to block a page from being indexed (which was never recommended) should use one of the much more robust mechanisms listed on our Learn how to block URLs from Google help page.
More detail in the article and the WebmasterWorld thread. To prevent confusion, I'm going to close our Sept 10 thread, and continue discussion here which will include the new attributes.
Also, please note that Barry at seroundtable has been on top of this with Google, and it appears that, thus far, Google has made no changes regarding "nofollow", so there's nothing yet to see. Here are two references...
UPDATED - WRONG: Google: Nofollow Hint Ranking Change Has Not Been Worked On Yet Feb 7, 2020 - by Barry Schwartz [

Google originally said they would make this change after March 1, 2020 but I guess it might be delayed a bit? // Just to clarify, prior to September 2019, Google would not crawl or index or use for ranking purposes {any} link with a nofollow on it (they would index the page linked to if there are other ways for Google to get to the page. After September 2019, Google would still not use it for crawling or indexing, but may use it for a hint. After March 1st, Google would also potentially be able to use nofollow links not just for ranking purposes but also for crawling and indexing, if it wanted to.
And, subsequently, with spectular animated gifs...
Google Nofollow Change March 1st But Google Says Don't Expect Any Change Yet Feb 28, 2020 - by Barry Schwartz [

I do think, btw, that Google has recently made some big algorithm changes having nothing directly to do with nofollow, and that by reserving the option to use "nofollow" as a hint, Google will eventually be able to do some more spidering to help calibrate and improve its new algorithms. As I had posted elsewhere on the web about this...
Way back, Matt Cutts stated that rel nofollow links were not crawled by Google, even for discovery. That said, I'm sure a lot of search engineers have looked at them (without Googlebot); and I'm thinking they've decided they wanted to go where no Googlebot has gone before. Thus...
