Indeed, looks like relatively low effort. I read the articles Payara and
TomEE have written about this (see
http://www.tomitribe.com/blog/2015/06/using-jcache-with-cdi/ for TomEE),
and compared to the effort JCache 1.0 took this seems absolutely minimal.
But even just making the existing API available in Java EE without any
integration whatsoever would already be a huge step forward.

It should absolutely not be a requirement of JCache to do this. The effort
has to be the other way around. E.g. JPA should build on JCache, and list
JCache as one of its requirements. This is pretty much like it now uses
BeanValidation and CDI. JCache should not know anything about JPA.
