I wonder what hurdles thememakers have to jump in order to make themes work on Etterna.

The "old scoring/grading system" isn't lost. A theme has access to the judgements and can calculate DP very easily(I think many vanilla SM5 themes did this).
Regarding themes, I think most/all SM5 themes should work on Etterna almost without any changes(Of course, they wouldn't use the new features).
