Question about threading backend

Hi!
I have a question about the threading backend. The mkl-fft package links the Single Dynamic Library, while mkl_intel_thread (prev. TBB) is used here.
The change to openmp is nice since I am using mkl_umath alongside other openmp-based packages.

If I manually build this package to use the MKL SDL, will there be any problems? Or do I need to choose a specific threading backend?
