So what happens if I try to _use_ that /sys entry? For instance run a 
script which reads data, or sets the stripe_cache_size higher, or 
whatever? Do I get back status, ignored, or system issues?

Try it:-)

The stripe_cache_size attributes will disappear (it is easy to remove
attributes, and stripe_cache_size is only meaningful for certain raid
levels).
Other attributes will return 0 or some equivalent, though I think
chunk_size will have the old value.
