Well, the cynics are often right :-).  But I think R7RS is intentionally much 
more conservative and R5RS-like.  In particular, it's *supposed* to be easy for 
an R5RS implementation to move to R7RS.  If it's easier to adopt, it's more 
likely to be adopted.

Scheme is rediculously non-portable due to its lack of a *standard* library 
system.  If a standard for *that* could be widely adopted, many other 
portability problems would be drastically reduced.

Indeed!
