Hmm. Could it be that the migration to KMail2 was attempted?

The simple answer is: Bad "design" decision in the past. In the past we 
used kmailrc for any (cached) information that we wanted to have 
available immediately after the start of KMail.

For things a normal user needs to edit there should be a GUI. For expert 
users there is akonadiconsole. For gurus there are config files. Nepomuk 
is a crucial ingredient for Akonadi. Without Nepomuk things like 
searching and tagging do not work.

In this version, only the address book requires Akonadi. Everything else 
works without Akonadi.
