This isn't at *all* true. LOTS of scheme programmers are brought up
using instructional Scheme environments that permit  as parentheses,
and are accustomed to having certain constructs in  instead of ().

Clearly you aren't convinced, and I believe you're probably in the
majority among this list's readers, but I've lately been teaching scheme
in an undergraduate programming languages course here at the UW and the
students definitely seem to like the ability to use , and find my
examples more clear when I reliably and consistently use  in certain
special forms (e.g., let bindings).
Bottom line is I thought the option would be nice. I'd expect it to be
pretty easy to verify empirically that programmers (especially novice
ones) can better understand Scheme programs that use  reliably and
consistently. (And I hypothesize little harm by random use of paird 
instead of () ).
So... my lips are sealed until I either have time to run the experiment
or can reference someone who has studied the issue empirically. :-)
