I seriously doubt that. The next app which uses ksycoca will rebuild it with 
the new version.

I think you're confusing this with "new symbols in kdelibs". *That* is what 
forces you to logout/login or run kdeinit4 in a terminal. This is due to the 
fork-and-load-module behavior of kdeinit4. Updating kdelibs breaks that, apps 
expect symbols that the old kdeinit4 doesn't provide.
