it makes zero sense to do kconfig -> uniconf -> INI in my opinion. to be 
perfectly honest, uniconf is exactly the wrong solution for cross desktop 
issue and exactly the right solution for legacy.

then and comment.

except the overhead for sharing! we're already fairly fast in this case.

then ffs get involved with:


you want to create a kdeconfigbackedn subclass ...

my job is to do what is best for kde. and in that scope, uniconf is not the 
future of kconfig. it is a future enhancement to it.

performance, flexibility, performance and the ability to decide our own fate.
