issue with trial / demo games

I removed the bad faith parts of your comment.

No. The previous behaviour was wrong, and you don't lose any data, you just need to move files around to their correct places now.

Any files in dev_hdd0/home/USERID/exdata that are in subdirectories (e.g. NPEA00001, etc) need to be moved to the main exdata directory.
If you have any files with the incorrect extensions, you need to name them with the proper extensions, as I already said above.
16 byte files are .rap, 352 byte files are .edat.

The behaviour described above matches the one on a real console.

As for you having manually deleted all of your licences and games, that's really your fault, why would you delete all of your games and licences without having a backup?

Also, to avoid confusion from new users, I have removed some of the older posts that had earlier wrong assumptions on them.
