Okay.

I just unsubscribed - I really wanted to understand how DSplayer can help kodi architecture and all users - but it seems there is no interest - as kodi does not matter at all - as long as the play button calls something else.

Unfortunately I think you missed the point. There are a number of solutions that would fit your statement (with and without Kodi). If people were satisfy with what you say there would not be any demand for DSPlayer as you could just use MPC or similar as an external player.

What is sought is a seamless Kodi experience that includes the feature set that DSPlayer (and MadVR) provides.

Fully right. But there is no way of merging (unmaintained) thousands lines of code - that doubles internal player structures - and benefit allover kodi. That step would not make kodi more maintainable but a whole lot less ... You would never ever add a second floor onto a broken baseplate - not if you would plan to live in there with your family ... but you would sanitize and repair the baseplate and when that is done you would think of extending giving base ... this is my point - I hope the picture helps.
