I'd say the Unix approach is equally flexible. 99% of programs
don't care about wildcard expansion, because the shell does all
the expansion for them. Programs that need to deal with wildcards,
like "find", can be invoked with their arguments quoted to inhibit
expansion.
That's why C's main() takes its arguments as a char** referring to
a list of strings, rather than as a single string. (See, it's at
least marginally topical.)
It's worked very well for 40 years. It can take some getting used
to if you're not accustomed to it, but I suggest that it's well
worth the effort.
(And even if you're right, and the rest of us have been doing it
wrong all this time, it's not going to change.)
One thing that *could* happen is that a new shell, or a new version
of an existing shell, could set an environment variable containing
the "raw" command line, before quoting and wildcard expansion.
But defining just what the "raw" command line is turns out to be
far from trivial -- and no currently existing programs make use of
the information.
