People have been using emoji comments to express not only reactions but also for voting. Even if you were to add voting features (which reaction emojis can be used for) you'd probably still get unbearable amounts of zero-value comments comprising of a single emoji, "+1" or gifs.

This is probably an attempt to break that "user habit" by providing a tempting alternative to the type of person who spams comments in issues.

Additionally, by using emojis for voting maintainers get slightly richer data about how users feel about something. A user story with 1000 thumbsups might fall lower in the backlog than a user story with 1000 hearts.
