Given the way MyISAM works, I would have thought it very unlikely that
this would ever happen. It would mean the SQL team developing their own
special-purpose file system. Why bother, when they already have such a
file system, called InnoDB? It is difficult to see what gain there would
be for investing a very large amount of effort which could probably better
spent elsewhere. As I understand it, the gains of using raw devices with
InnoDB are, while not zero, small.
Why do you want such a feature?
