I did read that article previously and was a bit disappointed that they hadn't already pushed it to on-premise without a full blown version change. I realize this has become the hot new trend for MS release patterns but you would think that their code base would be similar enough that they could push it to on-premise a bit more quickly.[/quote]
This "feature" has been a hot topic as to whether it should actually be in the product. There is one (undocumented) DMV in SQL Server 2017 that seems to pertain to this feature, but there is no data in it (yet). I think it will control whether indexes can be added or dropped - strictly a guess at this point.
