There is no attempt at depravation. It is rather the other way around. 
Unless you draw a clear distinction between the language and the
development environment, you can never ship without the development
environment because you don't know what you can seal off.  Smalltalk-80 was
notorious for this as you could not just "ship binaries"-- you had to ship
the development environment.  Languages such as Scheme or Dylan allow you
to cleanly seal off parts of all of a system.  You can link together an
application rather than just do image snapshots (much nicer to program your
car's engine controller with 1/2 8^).
