I’m switching the posting order around a bit as the gender and Haibane Renmei post is a) easier to write from memory, and b) doesn’t depend on certain key events needed to properly assess the dub.
When I’ve discussed this topic previously  I’ve had the benefit of a somewhat mixed cast to assess the gender roles against. So far the only male characters have been minor characters only, and who never become more than minor characters . There is one failed romantic interest with a male Haibane that pops up later, but I’m reserving comment on that .
The predominantly female cast does make assessing gender roles harder as there isn’t a mirror to compare to. The assessment is complicated by the protected / semi child like status of the Haibane, although somewhat offset by the requirement that the Haibane work. That the Haibane enjoy their work and generally flourish there also helps  to dent the image of dependency.
The general absence of fan service is obviously a plus, as are the generally sensible clothing choices , and the absence of any other alarming signals.
I think the final result is fairly good overall, primarily due to having a range of fully realised female characters who exist for themselves, rather than in relationship to a man.
