I'll keep this brief and to the point:
Note: there's some stories here that are missing from subscription and the magazine page, but are accessible via book pages. I've gotten conflicting responses from different FAKKU staff in the past about whether or not this is deliberate, so for completeness I keep including them in these lists.
If the book came out first, we don't do them when going back to an older magazine issue.
Bavel artbooks are typically done if we're sent the data. That was not the case for earlier issues, so don't expect those to be released.
I've fixed the Dascomi reprints in Bavel so they now display both magazines properly.
The Aoha chapters were doujinshi releases, and we could not publish those. I've added a disclaimer to the magazine.
Every other chapter listed is in the works.
As for the illustrations, I've passed that list along internally so we can look into those further.
