how do people play with different versions of DBSD on the same system?

When superVFS is in place, would we be able to have a /release,

Would it not be easier to install one instance of each and use the same
/home for all of them, that would probably work even for multiple BSDs.
My impression is (correct me if I'm wrong) that the main differences between
DEVELOPMENT, PREVIEW, and RELEASE are in the kernel, libraries, and toolchain,
in that order.  Userland changes are pretty minor. Having to download, build,
rebuild, configure, reconfigure the other 95% is a pain.
