The aim of Kronos and Zeus is to make XAPI available as a proper package
on various distros, there is no fork -- only effort to package things
for the particular distro packaging formats, which is normal for any
software -- or hack involved.

Part of Kronos has necessarily involved changes to the xapi side to make
it less entangled with XCP and therefore usable in a generic environment
(i.e. resolving the "distro-lock" which you refer to), this has
obviously made Zeus a fair bit easier.
