I think this is largely false. In order for the new syntax to be valid,

Consider that I have never dealt with the COM compatibility (or frankly,
even the extern(C++) compatibility) part of D whatsoever. Because I've
never implemented IUnknown, or used extern(C++).
I agree, I never used those either.
These features that are enabled by specific syntax are not extra
complexity for D.
Note that TDPL makes no mention of IUnknown or COM compatibility, yet I
have never seen a post on D.learn asking questions about this feature
set unless they were actually looking to write COM code. In other
words, no accidental enabling (I have seen questions as to why
interfaces are not Objects, and I grudgingly have to point to the
incorrect belief that COM objects cannot be discerned from normal D
objects at compile time).
On the other hand, something like shared and const are pervasive,
because they are core language features, AND because they are used
throughout libraries.
I think it is important to consider the applicability to normal code
when introducing such binding features. The way this is to be
introduced is the correct level of access -- only enabled with a
specific directive.
Well put, you said it better than I ever could.
