Symlinks in standard places should not be created, of course.
The shell and other commands could still be started by: busybox COMMAND ..."

Yes: busybox --install -s /some/where

Busybox may occasionally be useful because it provides lightweight 
versions of various commands (including daemons) not part of the Cygwin 
base installation and a few commands not available in any package.

It could also be used to build a minimalistic Cygwin (busybox.exe, 
mintty.exe, cygwin1.dll). If build with standalone option enabled, 
symlinks are not needed then.
