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. */ ;)
