Yes, I completely agree.  And would only make a difference for programs
that carry on meaning with their exit code, i.e., where the code depends
on the computation, as described in my use case.  The default use is
IMHO just error exit in programs, and most have it implemented this way
(think of clean-up at signal reception).  Having a default exit code of
124 is good for those standard programs.

Thank you, this sounds like good news!
