I suppose if, as has been my experience, “feature complete” actually means “whatever features ship with Exchange” then you’re right. But isn’t that the tautology of enterprise software? Vendors build a moat of features which end up in enterprise RFPs and ultimately lock out other vendors - not because the features are necessary or even useful, but just because they exist and, perhaps, some department head thinks it might be useful one day - or, more likely in my experience, the consulting firm involved in procurement gets a cut of the action. Having been on both sides of this process, I know exactly how it works in practice. So I’m sure that for some huge enterprises, the complete feature set from Exchange is actually necessary, or at least desirable. But for everyone else - including many companies I’ve worked in at a senior level, and almost certainly many of the victims of this vulnerability - I’d call shenanigans right back at you.
