Hinting is not really used nowadays; it made sense on low res displays, but not in HiDPI. You are better off with autohinter now. Wrt weights, fonts are not defined in pixels; so adjusting for this is the easy part. Yes, ignoring gamma is a problem, and I'm not sure whether anyone in Gnome/Freetype/Harbuzz is working on this; probably not. But this is a problem for low dpi and integer scaled hidpi too, not just for fractional scales. Widgets slightly shifted also mean your mouse is going to be shifted, and quite possibly in different direction. Now, that's going to be a problem, that the users can clearly reproduce.
