We have a fix for the comment reply link issue on the way. Thanks for letting us know.

I definitely agree that FSE is getting to that stage where it's ready for prime-time. It is by no means perfect yet, but I feel like it's important for a site like WP Tavern to be a pioneer. Actual real-world usage is where you really find the problems in the system, and that translates into feedback that makes it better for everyone.
