It's okay to disagree, but these have been the principles underlying
Emacs development since about forever, so please try to be consistent
with them as long as they are followed.  I don't think a case for
making Emacs Lisp a more restricted development environment than it is
now will gain many supporters.  E.g., even the move to make characters
a special data type separate from integers, something the XEmacs
actually did, was rejected by Emacs.
