More than annoying. I have been on contract with a company which has put their eggs in that basket so I imagine they won't be pleased. And I would imagine that will be an understatement.
Those who never use packaged apps will not miss them. For those who do it will require some thinking on how to rework things for non-Chrome OS users. Developing for Chrome OS made sense when packaged apps also catered for cross platform deployment, but when that is gone it is likely to be back to native app development and tough luck for Chrome OS users.
