/proc contains a lot of legacy junk but nowadays the trend is that you
should not add new files under /proc that are not process-related.
Changing /proc/mdstat is IMHO out of question since it is part of the
user visible ABI and breaking that is a big no-no. So if you want all
info in a single file that pretty much leaves only debugfs.
