First of all, savanna-extra has been created exactly for such needs - to store all stuff that we need but couldn't be placed to another repos. Initially it contains elements and pre-builded jar with Swift HCFS. Now the last one has been moved to the CDN and it's a good idea to make separated project for elements.
As for Swift HCFS the core attached to the HADOOP-8545 is targeted to the Hadoop 2 version and should be patched to work with Hadoop 1.X correctly. So, that's why we add it to the extra repo. It looks like that it's ok to add one more repo for Swift HCFS near the savanna at stackforge like HCFS for Gluster.
So, let's discuss both of the migrations at the next IRC team meeting.
