In some fields having it be pre-published pretty much disqualifies that work to be ever published in a way that "counts" as almost all high impact factor journals will only consider unpublished research, so placing it in arXiv means that this research will never be considered 'quality' by the formal criteria and the work is wasted from the perspective of fulfilling the obligations towards the funding source which required Q1 publications.
