Why would they? The API they (WebKit) are providing is the Canvas API, the fact that they're using Skia behind the scenes is an implementation detail... I don't see why they would go through the trouble of maintaining a stable C API for internal use in a C++ project?

Maybe so they could use newer versions of skia

This assumes that maintaining a stable C interface to Skia, and then writing the WebKit rendering code against that C interface, is easier than maintaining WebKit rendering code which calls Skia's C++ interface directly. I'm not convinced that that's the case.

At the very least, the stable interface should probably be C++, mapping between C and C++ is often non-trivial...
