There is nothing bad with kernfs, and actually it doesn't matter if the
symbol table is accessible both through kernfs and /dev/ksyms (like
/kern/msgbuf vs /dev/klog, although a little bit different).
I am also rather sure that noone have been thinking about making
ksyms/kernel-ld/lkm non-optional: If you have a system that is sparse
on memory you probably want a small static linked kernel without
any extra facilities. I would for sure not generate in any kernel
symbol tables and loaders in a 5MB MicroVAX II :-)
I don't see anything wrong with adding new well-defined functionality
as long as it is optional.
