Yep, that's perfectly fine, it's the definition of tier3, see the first 
section in http://community.kde.org/Frameworks/Policies.

Tier4 is very special: it's for things that offer additional integration 
automatically (without providing an API, so more like plugins).
And for things which are deprecated and sit on top of everything else.

In other words: "pure-KF5" applications shouldn't link to anything from tier4.

The API layer stops at tier3.
