Thank you for providing your feedback on this suggestion.
Unfortunately, we have no plans to implement this suggestion for pages or spaces (see my final paragraph for blogs). As a result, we're closing this request.
Based on customer feedback, we’ve worked hard to reduce the amount of email notifications end-users receive. We’re concerned that implementing a group watchers feature has the potential to undo these past improvements.
In enabling group watchers, users added as watchers of a page or space via this functionality would be unable to remove themselves. This has the potential to create a greater level of frustration for some users compared to the benefits this feature might bring.
As I’m sure many of you are aware, there are multiple workarounds available to address this issue:
We do however see potential future value in allowing group watchers for blogs. Unless a specific blog post is being watched, blog notifications will only trigger when a blog is created, so can be invaluable for sharing information with a large audience. If you're interested in managing group and individual watchers for blogs, please vote on CONFSERVER-24353, or the related CONFSERVER-30644.
