For the other persistence frameworks, I think the "bridge" was built by
DataNucleus (source seem to be included in the SDK).
DataNucleus however didn't noticed Cayenne yet :(.

This is also a problem for the users that would like to use it: they have a
hard time convincing project managers (not because of some missing standard or
feature, but because of "critical mass" and visibility - many don't even know
that it exists).
I also believe Maven is a deal breaker (like a warning sign) for most new users
to try explore the internals of Cayenne.
