While design hand off, devs/PMs often use Figma as the sole source of truth. But, the overwhelming no. of comments scares them away and they end up missing important comments. This leads to a lot miscommunication and redundant discussions, especially in hybrid work environment.
Instead, by default, if a user only sees comments or threads that they are a part of - it would be quite easy to propagate and communicate designs. It will also lead to a more involved participation from across the teams.
I am aware of the cases where users may forget to mention somebody, and then users will anyway have to use the sort action to see comments. But I guess, this trade off can be afforded?
