Unlikely to happen because:
- Writing a sync service from 0 is a gigantic pain
- Akonadi is incredibly powerful and handles most of what anyone would need from a sync service
- Akonadi has a sensible and easy-to-use API that apps like Kalendar can leverage
- There is no alternative that uses KDE APIs that is under active maintenance
Not saying Akonadi doesn't have big issues, but it is a good base. It just needs more love -- love it hasn't really gotten!
I think it is important to note the human element here: an incredible amount of effort went into creating a super powerful PIM framework, and then many people piled on to criticise it -- some for better reasons than others.
It is natural for the response to sometimes be overly defensive in reaction to these things. Again, as a PIM developer myself -- Akonadi often gets more flak than it deserves, though I also agree some changes are needed.
Disrupting lives and work of hundreds of thousands of users, just because they decided that "it's ready" when it was anything but.
That is no way to treat your userbase. And yes, it's a FLOSS project, so technically users are not owed anything, but in that case the devs need to deal with the criticism.
