In theory, this sounds good. However, it would be great if you could direct us to where we can find more detail on particular points, as the articles linked are really general.
The article linked above says: "For example, along with finding a guest’s overall rating, you’ll know how other Hosts rated them on cleanliness, communication, and following house rules."
But, this is nothing new at all. We have rated guests on these categories for years, and have been able to see those ratings from their previous stays for quite a while now. It would be far more useful if the article explained the addition of the 'extra details' that hosts are now able to supply.
In Brian Chesky's video (the one aimed at existing hosts, other than at attracting new ones), about 2 minutes, 15 seconds in, he starts speaking about this briefly and you can see here an example of the additional details he's referring to:

Where can we find out more about this or see the full listing of options? I assume there are more, e.g. regards smoking for example. And, if they are already in effect, why is @Gillian166 not seeing those when she goes to leave a review?
As for the details a guest can now leave in addition to their ratings, above you've mentioned that the guest can "now add a star rating...in several categories." Again, they have always been able to do that, at leat as long as I've been hosting.
Then the article says: "For example, if your place is super clean, a guest might choose five stars and “squeaky-clean bathroom.”" Again, is this new? We had something like this a few years back, only it was called highlights or something, and a guest could choose "sparkling clean" I think it was. Some of those highlights would then appear on the listing, but a lot of hosts didn't like this for a number of reasons, so I assume that's why Airbnb scrapped it. Are we now to assume that these comments will be visible only to the host they are being left for, or will they be publicly visible?
RE ground rules for guests, the article on that says that the house rules will now be displayed more prominently, including on our listings. Well, I just went to check one of my listings and I can't see how it's more prominent. The basic house rules are still displayed at the bottom page, rules/policies, which was once one of the menu tabs that used to display at the top of the listing or whilst scrolling, is still not there. Again, is this something that is supposed to be in effect already or still to be rolled out?
Sorry for all the questions, but these articles are really vague and often presenting existing features as something new.
