Perfect sense historically, yes, but that doesn't make it right or healthy. Vows of Celibacy are a huge issue wherever they are. Human beings were not designed for it, and have a healthy need for emotional attachement. Case in point, the Jedi being treated as psuedo villains and needing to be re-structured. If they go back to celibacy Anakin's fall did nothing good.(Just saying)
Yea I wouldn't hold out hope for Thrawn or Mara. Maybe Luke made the Jedi Order like of old, and made them celibate (a concept I find ironic when you're supposed to be connected to everything but you can't connect with anyone).
Others have criticized Lucas about this aspect of the Jedi code but he was using real-world ascetics as archetypes. Look into the rationale for why some monks take vows of celibacy and I think you'll see that it makes perfect sense for Jedi.
In Jedi terms, I don't think it matters. It's a fictional order of warrior-monks and if celibacy is part of the deal then it can be a source of dramatic conflict (as we see with Anakin, and creepily but briefly with film-Luke) or not (as we see with the rest of the film-Jedi).
Since there is no obvious casting for a romantic partner for Luke in Episode 7, I'm assuming celibacy is still part of the Jedi code -- but that's assuming that Luke is still a Jedi, or that the Jedi Order or Jedi code has any meaning any more.
