As I told Federico, I may have rushed this change yesterday, but my
fear is that I'll spend the week running after the white rabbit.

My take on this is that I don't care breaking stuff on a major release
that already breaks other areas.

If there's a better place for the public APIs (maybe vrt.h) then let's
move them there.

As I also told yesterday, that may make things seemingly simpler, but
I think it would be even more confusing wrt what you could actually
use or not.
