--- Comment #10 from Christoph Feck <cfeck at kde.org> ---
> No user with a HDD will ever report a single bug about slow application startup for nearly 1 more second at the start of Plasma (which is an example of when to load the icons because all icons are loaded, not only those of Kate).

Here is your misunderstanding. You cannot load all icons in advance for all
applications in a separate process. Each process needs it's own QPixmap
instance, and each process needs to load them from the icon cache either on
each application start, or at the moment they are actually needed.

We opted for the latter, because loading all icons even those that are not
needed yet increase both the memory pressure, as well delay the application
startup.
