I think this is a very reasonable suggestion, so +1 from me as well.
But I'd like to point out the shellquote() function, which can give you
the semantics of the first version already today:
exec { "foo": command => shellquote("/bin/ls", "|", "foo"); }
(There's actually a slight difference. Using shellquote() today will
give you an intermediate shell process, making it somewhat less efficient.)
