I think what most references to this are asking is if one has taken the time to build a new kernel version of PUP528, might they have taken the extra step to have added the update built into the ISO?... new 3.0.4 528 have the new update to 528 installed in it already? ...
NOT being a distro developer, I am not sure if this would have impacted the deliverable.
My questions, though, is wondering whether the distro developer wants us to use this distro without the update or does he want the updates added?
If so, how would he be able to distinguish which bug fix he is working on; namely non-updated problem or updated problem?
Just some thoughts, about the advice the developer might want to give this user community.
This PUP is, though, a great step forward no matter which advice is offered.
Hope this helps
