This would be a really valuable addition to allow improved visibility for escalation of posts to an entire group IE: Support Teams rather then having to mention all the individuals on said teams.

Love the idea, but I would restrict feature that to admins and moderators. Otherwise that quickly would spam hard if everybody can notify the whole community in every post.

This is something that has come up a few times. As mentioned, it would quickly turn into a spamming feature (you only need to look at facebook to see that). So the instinct would be, as you say, to allow only admin and moderators to use it. The problem with this, is it would also quickly annoy members if they are being mass tagged in things. Admin and Moderators also already have the ability to get information to members if needed, by way of alerts and announcements, so it would add very little value.
