I honestly liked better the old names, VersioningFeatureSource and
VersioningFeatureStore.

If you look into the existing naming conventions we have
ReprojectingFeatureCollection,
not FeatureReprojecting, ForceCoordinateFeatureReader, not
FeatureForce and so on.
The proposed naming would be uncharacteristic and suprising to the geotools
user. -1 on it.

I know that OpenGeo is working on a distributed geographic version control
system inspired by Git, GeoGit:
https://github.com/opengeo/GeoGIT

One thing that has always been missing from the old versioning API is the
second and third implementation (they say you need at least three different
implementations to nail down an interface).
Would be interesting to get a perspective from Gabriel on the proposed
interfaces and see if there is maybe small changes that could make
a GeoGit based versioning system more "eager" to implement the
versioning interfaces
