Side by side needs a bit adaption e.g. translation files have right now
no Major version in their name.

But the interesting thing will be kipi-plugins.  When kipi-plugins is
build against libkipi.so.x+1.0.0  an app linked against the old 
libkipi.x.0.0 can not find the kipi-plugins.  Of course we can also
adapt kipi-plugins to stay side by side.

Distros and pkger will surely be not happy to maintain old and new
kipi-plugins side by side.  I assume that they much perfer a patch
that adapts gwenview to new kipi-plugins, that they can apply.

But all this is only a problem when the api changes. It can always
be extended.
