Years later, kmail still is not a viable email client?

Well, problem is that Akonadi is responsible for storing, indexing, searching 
and presenting data. Which is like 90% of what mail clients are actually 
doing. This means that It is actually almost the same amount of work to write 
new email client from scratch then to remove akonadi from KDE PIM. Therefore 
if kmail does not work for a user (it works for me perfectly fine) why he 
would insist to rewrite kmail instead of simply using other "lightweight" 
email client? Rewrite is not guaranteed to be bug free, in fact at least 
initially it would probably be very buggy which would actually downgrade 
experience of fortunate current users satisfied with the software.
