We have (had) a policy that no application-module-library should used
by applications outside that module.

i.e we can't have kphotoalbum dependent on libkdcraw from kdegraphics

I think this is still a good policy.

But we know that digikam, kphotoalbum, etc. does rely on libs from kdegraphics.

If we put such libs in a new module called kdegraphicslibs and enforce the ABI/API
restrictions there, then we can eliminate these problems in the future.

I think kdepimlibs has proven this to be a successful strategy.
Lots of non-kdepim stuff depends on kdepimlibs and we haven't had
ABI/API complaints problems from that combination in a long time.

Some libraries are widely used and can conceptually be thought of as core libs.
Perhaps libkdcraw is such a library.
