I think the 'strictness' comes from the fact the /proc system was
heavily abused for dumping just about any info into it (in the early
days 2.4 kernel, I think).

/proc was originally meant for putting 'process' specific info (thats
why the name - proc) and not for device drivers. CMIIW.

sysfs is a dedicated place for device drivers to export info to userland.
