C vs C++ Device Driver Question

On the MS website: http://www.microsoft.com/whdc/driver/kernel/KMcode.mspx
it points out the many pitfalls of developing a kernel mode driver using C++
(classes, inheritance etc.).

If it presents so many problems to use C++, why do the AVStream samples use
C++ classes?
For example in C:\WINDDK\3790.1830\src\wdm\avstream or
C:\WINDDK\6000\src\AVStream, the sample
files provided by MS contain C++ classes, and use inheritance!!

Since especially the avshws sample is targeted for eventual use with
hardware( it is pin-centric, shows how to
do DMA etc.), why is it not written in C, like the bulkusb sample for
example?

What does the community think about using C++ in kernel mode drivers?

Thanks
