DSPlayer could be maintained as a side growing project for videophiles which happend to be windows exclusive while kodi mainline stuff keep getting optimized to the point where dsplayer is not needed anymore.

Which features from dsplayer/madvr do you want?

I think kodi needs better scalers with antiringing, debanding and maybe some sharpeners for people with big gpu.
I know there are some available opengl shaders on github like nnedi3, super-xbr, debanding, lumasharpen, adaptive-sharpen and more.
But I am not a developer at all and I don't know if they could work with the new kodi videoplayer on all platforms.

Yes - all this is needed. But we don't have anyone that is doing it - kodi core team (those that regularly write code) are arround 10 people ... for Windows, Linux, IOS, MAC OSX, Raspberry Pi, IMX, Android ... so if you love kodi and want to help us, help us cleaning our year grown architecture mess and then contribute small things that help all of us - scaling shader / sharpening that can be easily integrated.
