This is not true. Just have a look what hush in a recent version of
Busybox offers.

Oh, this is an interesting opinion. I doubt if a majority (or even
a significant percentage) of U-Boot users share it. If you were
right, there would be far less users of bash (or other "bourne
derived shells"). Guess which percentage of users of UNIX operating
systems is using a Tcl based command interpreter as their login
shell?
Best regards,
Wolfgang Denk
