While perfectly understanding the weak collaboration model reasoning, I've still always found DPT as uploader and not maintainer rather absurd TBH. The current go to tool (as I understand it) for python packaging, py2dsp, also creates an initial packaging with team in uploaders section and the person as maintainer; something that I find even more absurd. Not only would I welcome this suggested change, I also think it is better if py2dsp default to starting with DPT as maintainers.
