Changing inout to ref would be a very long process in several stages:

1) Adding ref as a keyword and documenting its usage
2) Recommending changing usage from 'inout' to 'ref'
3) Removing 'inout' from the documentation
4) Producing a warning on 'inout' with -w switch
5) Deprecating 'inout'
6) Removing 'inout' as keyword

Also, 'inout' is easily greppable, and very likely is unique enough that 
using nothing more than a global search/replace will work.
