Why are we not using libbacktrace for backtrace?

GDC uses libbacktrace since 2013: https://github.com/D-Programming-GDC/
GDC/blob/master/libphobos/libdruntime/gcc/backtrace.d

I think the main problem for DMD/LDC is that libbacktrace is not an 
installed library, it's only available while building GCC.
