Quite a large number of packages (including almost all using S4 methods) 
*do not work* without lazyloading or saved images.  So this option would 
just break other people's work.

Rcmdr comes with LazyLoad: no in its DESCRIPTION file (so I have no idea 
why you need to do anything different).  John Fox and I worked out why 
this was needed, and that lazy loading was not helpful as that package 
does access almost all its code at startup.
