That is a valid point and is always a case with so many drivers. What
I am concerned about is how much code is common across versions, if it
is 5-70%, or more, then we should definitely share, arrange to have
callbacks or ops per version and call them in a generic fashion instead
of writing a new driver. This is what's done across
drivers/frameworks, etc.
