That aspect of the GPL is what any software end-user should want, all the source code, for every part of what you are using. It is a shame Oracle hasn't released a CDDLv2 that provides GPL compatibility, they could solve the incompatibility quite easily, since CDDLv1 has an auto-update clause by default. I think some of OpenZFS has CDDLv1-only code, but that could probably be removed or replaced.
