I think the main value is in not using xpidl anymore, for two reasons:
1) You can't devirtualize things while still using xpidl. Removing
xpidl bits means your objects might get smaller (fewer vtable pointers),
our relocatable data gets smaller (fewer vtables), and runtime likely
gets faster.
2) It's hard to get sane C++ method signatures while using xpidl. You
_can_ do it with [notxpcom,nostdcall] and enought native-type
declaration. But it requires some hoop-jumping. And at that point
what's the benefit of using xpidl for it?
