Actually its for the better. So MS extended the mainstream support for another 6 months in terms of servicing and support. Plus another 6 month paid servicing only. So you get one more year quality updates if you want.
Just to clarify what servicing and support means:
- With servicing you receive public available quality updates. This does not include private hotfixes if needed.
- Support means you can also call in and get potentially a private fix if its a bug. And it includes the quality updates from servicing as well.
