I probably use the mule-ucs package once a year, but to have it installed means that it gets loaded every time I start emacs.
Perhaps dpkg-reconfigure mule-ucs [and other hefty packages] could ask if one wants to have the package on one's system, but not loaded. One might say one could just install and remove the package when needed. But for offline users, that is bad. By the way, if in the future dpkg-reconfigure will be used to set non-loading, it shouldn't go ahead and do remove/mule-ucs: Handling removal of emacsen flavor emacs21 ... done. install/mule-ucs: Byte-compiling for emacs21 ...This will take a while ... done. if not necessary.
