I do love it when personal bias feeds into people spouting opinion as fact.. Anyway, like Chainz, I will try and continue a mature discussion which doesn't reduce to name calling, hair pulling, and "so do it then if it's so easy" comments.
Windows Phone transitions to Windows 10 Mobile and becomes the OS that will be used not only on phones, but on phablets/mini-tablets up to 8" in screen size. For now, lets ignore the fact that Windows Phone outsells iPhone in over 20 countries. yes, many are developing countries but guess what - there's a lot more people in those countries which means more handsets. Anyway, I digress..
Windows 10 gets released in less than 3 weeks' time. It is a free upgrade available to quite literally ever user of Windows 7 and Windows 8/8.1 which is many millions of users.
Then you have Universal App model that makes it possible to develop an app that can be pushed to both Windows 10 and Windows 10 Mobile with minimal (yes, very dependent on style of app I appreciate) difference between code compiled. technically, this will also be able to be extended to Xbox One when it is upgraded to the new OS based on Win 10 code later this year (I have many friends that LOVE Plex on Xbox One).
Even with Bridges, I don't see the value in porting the Android version which appears to be less mature and feature rich than the Windows version.
Anyway, the devs get to manage and control roadmap as it is their time, passion, knowledge, and ability that lets the rest of us benefit from a great product. I'm more than happy running Kodi on my 3 x Windows HTPCs that will all get upgraded to Windows 10 in a few weeks' time. Even if there was a Windows Phone/Windows 10 Mobile version, with the way, types, and times I consume media on my mobile I wouldn't use it much. An Xbox One version I would definitely use.. on both of my Xbox One consoles
