Nonsense. You are trying to make a distinction WHICH DOES NOT EXIST
IN REALITY.

Which is completely irrelevant to the question at hand.
Question for you:
Why the h*** do you care that cron runs a shell? What does
the shell do that is so horrid that you want to break cron?
What makes you think that every !@#$%^ utility in the system
needs to parse command lines when there is one program (the
Bourne shell) whose sole purpose is to do precisely that?
BTW, this is from crontab(5):
The ``sixth'' field (the rest of the line) specifies the
command to be run. The entire command portion of the
line, up to a newline or % character, will be executed by
/bin/sh or by the shell specified in the SHELL variable of
the cronfile. Percent-signs (%) in the command, unless
escaped with backslash (\), will be changed into newline
characters, and all data after the first % will be sent to
the command as standard input.
