Adding any emoji as a reaction remains under review.
I am marking this as partially done to let you know a new reactions bar with Like, Heart, Laugh, Surprised, Sad, and Angry has begun rolling out to all users.

I'm happy with just the thumbs up, in that style that it was in. Also, it's nice to have just one button to click. Hovering and bringing up a menu and moving over to the reaction you want— too much.
Teams is great! Thank you guys for all the work you're doing!
