Why is native BPEL important? What is the disadvantage of products that only import/export BPEL?
Historically every time a standard has been adopted (SQL, J2EE, LDAP, SMTP/POP/IMAP, HTML, etc.), native solutions have won. It is because native solutions are less complex, faster and offer richer functionality. It is also because re-architecting an engine around a new abstraction is very difficult, especially if you have an existing install base that you need to maintain and evolve in parallel.
