It is a commonly used feature, since many C++ programming standards, 
many C++ projects, and many companies do not use exceptions in their C++ 
code.  A prime example is Google, whose coding standard disallows 
exceptions.  Another is the small embedded systems programming world 
(roughly speaking, systems where the processor runs a single program 
rather than an OS supporting multiple programs) where disabling 
exceptions and RTTI is the norm.  You will also find exceptions to be 
disabled in many high-performance coding tasks, such as games.

Exceptions are definitely useful for many purposes, but equally 
definitely not ideal in all systems.  It is not a surprise that various 
"error return" mechanisms such as "expected" and "optional" are on the 
uptake.  The proposals for a more lightweight and deterministic 
exception mechanism may turn out to be a better compromise between 
different error-handling solutions.
