[openstack-dev] [nova] Should we cleanup migration from virt drivers?

hello Nova hackers

I see in some of virt drivers (see belows links) 's 
confirm_resize/revert_resize(or something like that) passing a parameter 
'migration',
but it is not used at all in virt layer drivers, I wonder why we still 
keep them (to reserved for future usage)? can we do a cleanup?
IMO, migration status should be maintained by nova compute layer instead 
of virt layer.
