That's a bit of a false dichotomy. The majority of people that would be working on the warbond (marketing, artists, system designers, etc) wouldn't be able to fix whatever bug made you fall out of your ship. They should still absolutely fix the bugs and crashes and everything else but most of the effort that went into the weapons isn't going to detract from fixes and quality of life.
They have outright said that bug fixing has been difficult because they are dead set on keeping the promised warbond schedule. That definitely implies the two compete for resources, even if it isn't a complete overlap. That said, I'm not sure how delaying this warbond, which is presumably just about finished, will help that but I would prefer a delayed warbond or two if it helped clean up the issues.
