That's OK.

file_db_data is massive indeed, though for me more in number of files (over 5000) than bytes-on-disk (59Mb with ZFS lz4 compression which works nicely on text).

Still, would you incur a big performance penalty using libzip or some such (leveldb?) to store all those files in an indexed, compressed archive.
A massive directory containing (tens of) thousands of files isn't exactly efficient (and probably even more massive in terms of actual disk (sector) usage).
I should probably spin this off to a separate thread.

Yes, it is - as you say, adapting it to KF5 shouldn't be hard.

.kde/share/apps/korganizer is missing? 
I also see only ~/.local/share equivalences for .kde/share/apps/kabc and korganizer, is that because there are none?

Since KF5 or already since a 4.1x release?

>(sometimes also ~/.local/share/.local-mail)

Distro-weirdness I presume. Why would they do that...?
