 Yes, variants are a great idea.

 My personal preference would be default OpenMP support because
 multithreading makes my code scream on large graphs, and all my boxes have
 multiple cores anyway. I suspect this is common among graph-tool users,
 although I'd defer to Tiago or others who have experience with omp build
 robustness.
