I feel like what she got - as sad and limited as it was - was fitting. The whole reason she sacrificed herself was because she knew she'd be missed less than Clint would, and she wasn't wrong. She had very few friends, no family, and basically no life outside of superheroing (and even that, she wasn't exactly top-tier at). A funeral anywhere close to the scale of Tony's would just feel contrived and implausible, since there simply weren't enough people in the world who cared about her enough to attend, nor enough people that she cared enough about to want them there. Bruce, Clint, and Steve mourned her at the time, but they're really the only ones who were actually devastated by losing her. If there were to be a farewell scene, it'd pretty much just be those three reminiscing over beer, not an actual memorial service, and I don't think it's altogether necessary to explicitly film that. ---
