Bronson Reed was Main Roster Bound, hell he worked Dark matches at RAW/SD. Tyler Rust is currently part of Diamond Mine, but he's easily replaceable as the group is based around Roderick Strong. Jake Atlas has been featured on TV in spurts.
But the biggest stupid about this is that the releases happened DURING Smackdown. I mean seriously that's stupid ass timing. Do it in the morning, do it over the Weekend. But NOT when your company is currently airing your biggest show on NETWORK TELEVISION.
