there is JCR-Yarep implementation which is using Apache Jackrabbit, 
which means yes ;-) but

it doesn't, it's using Yarep as data abstraction layer, but in the 
sample realms the file system implementations of yarep are being used 
and hence you can see the data within the filesystem, but you can easily 
switch.

Yarep also contains a utility to migrate your data from one 
implementation into another one, e.g. from virtual filesystem to eXist.

agreed, but the key is the data abstraction layer which is hiding the 
actual implementation. So maybe eXist is a better implementation than 
others, but the application itself is never seeing this implementation, 
but only the API, e.g. JCR or Yarep.
