You need to understand that s/w market is driven by standards and companies wants to follow/use those technologies that has its proven records as far as its usage is concerned. The Written code should be easier to code and Maintain too. Examples like Hibernate, EJb,iBaTis, toplink etc etc. These all followed JPA specification(s). JPA means nothing more than a standards.
However I would agree that JPA Specifications are subset of what is being followed by Hibernate and others.. Some like this.. Code for JPA not for EJB.

iBatis is not a JPA implementation.

think of the advantages brought to us by JDBC on connecting databases.
JPA will do similar benefit for POJOs access to database.

Hibernate already supports JPA,Apache Cayenne announced upcoming support,Oracle has java version of toplink supporting JPA,there is also OpenJPA..
