Domain mapping plugin 302 redirect issue from 7 months ago still occurring

As discussed in the following thread 7 months ago ( https://premium.wpmudev.org/forums/topic/domain-mapped-subdomains-using-302-redirect ), the domain mapping plugin is redirecting using a temporary 302 vs 301 redirect. It doesn't look like the fix that was discussed was ever implemented. I think the reasons for why this is undesirable are self explanatory, can we get this fixed?
