The worst situation would be to have to support both, so I imagine once we've decided one way or the other we'll deprecated the other method. > > Is it just shortage of space, or is there anything else that pushes you towards DYNAMIC_GHC_PROGRAMS=NO?

Speaking for myself, but I've noticed compilation times can be much shorter with DYNAMIC_GHC_PROGRAMS=NO. On one project using dynamic ghc added about 18 minutes to the build time (45 minutes vs 27). That's significant enough that we're leaning towards static ghc for now.
