The modmakers don't suffer too dearly, blueprint can do almost anything a modmaker could want, and in the future perhaps we can drop the almost.
They didn't really drop the highlevel language, they just dropped the idea of a highlevel general purpose language, favouring a strict DSL.
There's still a bit of interop, but you have to be very explicit about it. In C++ you use macro's to tell the compiler what's accessible to blueprint, and to access blueprint from C++ you have to make weird queries that are very obviously highly dynamic and ill-performant.

So cool stuff all around :)
