Would we really be better off if we switch to some exotic piece of
code instead (I was not able to locate any user base, nor other
developers), which has been reported to have poor or no error
handling, and comes with an incompatible command line interface?

There is a zillion of shell scripts in the field, from non-trivial
boot sequences to complex download-and-upgrade scripts. You can't
really even think of breaking compatibility on such a level.

Best regards,

Wolfgang Denk
