Functions COM functions SysAllocString / SysFreeString require calling CoInitialize?

Is COM initialization required to use SysAllocString, SysFreeString, and other BSTR processing functions?

MSDN says

You need to initialize the COM library in the stream before you call any of the library functions except CoGetMalloc

It seems to me that the BSTR distribution functions use IMalloc, and therefore no COM init is required?

I can't find the official documentation that says you can call these functions without initializing COM, but I can take you on the way down the memory strip for some nice observations.
