Hope this explains things from one old programmer to another! Hope the wine was good.

I agree with you in that I am going to avoid KFX for archival of my purchases as long as possible by making use of an older Kindle. I expect it will be several years before KFX becomes a real hindrance to me, if ever. I believe that there are enough older Kindles to go around for the small percentage of Amazon customers that care about archival and format conversion. KFX can be avoided by those who care enough to do so.
Still, I enjoyed looking into the new file format to try to tease out some the secrets of how it works, even if there was no practical benefit to the effort.
(And the wine was very good!)

I looked into converting unencrypted KFX from Kindle Previewer 3 back into EPUB and had some success with one book with simple formatting. But that was almost a year ago and I don't have anything shareable left over from then.
