Besides, it's not like we're asking for her to come back immediately, just bring her back eventually. Don't hang a lantern on her story and forget about her. Could you do that to Picard? Or Sisko? Or Kirk? Or any other character from Star Trek???
Actually some people are demanding that she be resurrected immediately. In fact, some of the people here have been demanding it since it happened.
I've said before that I would have no objection to them writing stories about Janeway's adventures set prior to her death (say during the journey across the Delta Quadrant). But she should NOT be brought back from the dead. Like Kirk, tell stories set during her lifetime, but don't resurrect her for stories set in the 2380s.
