It was originally going to scream and draw a horde. But playtesters found that it was far too hard to find and kill during a horde, or really just on his own. So, the screamer was scrapped, and the boomer vomit was given the ability to call a horde

Yeah, old news. It's mentioned in the dev commentary too. It was too impractical to make the cut.

Please use the search button in the future. That's a clip from the developer commentary, which has lots of fun facts about the development. It's worth listening to.
