As an ISV providing a SharePoint based ECM solution to large customers, we very much appreciate that you strive to optimize the customer value and focus on security – well done.
However, we are disapointed that you don’t provide any real alternative to the functioanlity that you deprecate. Let me be specific on what I mean. Currently we use RER in two scenarios
- Due to compliance reasons we have implemented “Blocked file types” supporting both a white list and black list functioanlity. It is implemented using ItemAdding, where we can cancel the opeperation causing SharePoint UI to show a nice error message to the user.
Removing syncronious ItemAdding leaves us with no alternative way to implement this!
- We implemented automatically meta data tagging on documents using the ItemAdded event. You can claim that we just have to use Webhooks istead. However, with many solutions with 100.000+ sites, it will be a nightmare to maintain experation/renewal for all these webhooks. It’s simple not enterprise architecture!
