It's in large part cultural. I came to the embedded world from writing
large apps on workstations. Most of the embedded software people were
more hardware oriented. We had very little in common. Fortunately
we could divide the work along the lines of hardware/ISR/driver and
the rest the software. OO and C++ were seen a slow, bloated, and
unecessary.

As exceptions haven't been thread safe so i really haven't had a chance
to consider this :-)

A big issue is changing configurations on the fly without
rebooting. This is very difficult and is very common.
