Hey Justin! I'm back and have the updated post for you fresh off the press: https://make.wordpress.org/core/2022/04/22/status-of-webfonts-api-for-wordpress-6-0-inclusion/

As for the impact on style variations, the approach described above in the post would allow style variations to function as expected for this release with different font offerings. This assumes the approach works and is shipped of course :). Anyone reading this who is keen to test and wants to see this feature in place for themes, please help out. It will help immensely.

As for the post author name block, I agree with what you said here: "It is an obvious pairing for the new Post Author Biography block and almost feels necessary for Author Template support.". It's been a big piece of feedback for the latest call for testing for the FSE Outreach Program. Here's some back and forth about this in a GitHub issue: https://github.com/WordPress/gutenberg/issues/24952

I ultimately think what Ben said at the end both makes sense and is a bummer: the author template simply won't be as high impact for now. Once more, it leaves something to look forward to in future releases :)
