Well, the short answer is: You can't. The longer answer is that there's
probably a way of moving out the vcs-specific codebases into separate
libraries/plugins (KDE-API on top of the actual backend as far as
possible).  That would allow sharing the code that interacts with the
vcs API/process and provide a vcs-independent API on top of that.

What would be needed for that is a library that provides basically the
same as the current kdevplatformvcs library (regarding interfaces and
classes) and adding a mechanism to query for the interfaces in some way
- i.e. something like VcsSystem::basicVcsInterface( <somelocalurl> ).

The kdevplatform plugins would then use this instead of the backend API
directly to implement the kdevplatformvcs API (not sure if we coudl
re-use the interface-classes from the library).

One thing that definetly doesn't work (for KDevelops use-case) is a
kio-service. We had that in kdevelop3 and kio is just not meant for
that from my experience.
