Good point.

Interactively, I would rather like to have a default, but of course in a 
notebook (or similar) I would go with the Zen ("explicit is better…").  Maybe 
that explains the two opinions.

A solution could be to require a specification, but offer completion (e.g. 
from /etc/shells, with $SHELL being the default)?

Also note that %%script could remind of the 'script' program, whose main 
purpose is to copy(/tee) the fds 0,1,2 into a file.  That 'script' also has a 
default but allows selection with "-c command".

Best regards,
  Hans
