I don't know.  Maybe nobody uses them (anymore/ever)?  Nobody tried to
rmmod the kernel module or compiled the driver into the kernel?

The solution to the problem (if someone encountered it) was probably
policy-based: just don't unload the module.  The comment in lp.c is
clear: /* Write this some day.  */ ;)
