At this point just having root would be like winning a lottery with 4.4, and of course 4.4.2 would be nice as long as it's rootable as well. I got no real issues with the phone itself (the Droid Mini), and I have to admit I'm just sick and tired of dealing with custom ROMs (been doing that for over a decade now on 100+ devices), it's pretty much boring to me nowadays.
I just want a device that works, is rootable so I can run some things that legitimately require it (Titanium Backup primarily, a few others), a kernel that allows for some better performance adjustments and governors with tools like SetCPU or nowadays I prefer Trickster MOD for that stuff, and gives me battery life that I can reasonably count on, and a few tweaks here and there - my one big tweak that I really miss nowadays is using the volume buttons to skip tracks during music playback (screen off) since Motorola just won't put a damned TRRS headphone jack in their devices that allows for actual remotes that work on the headset cords - wonder why they refuse to do that so steadfastly... makes no damned sense to me. Samsung and Apple understand it matters and there's no issue with their devices, can't speak for HTC since I don't mess with their stuff anymore but it sure would have been nice to have proper volume/playback controls for these Motorola devices.
4.4 on the Droid Mini isn't doing that, obviously, at least not as well as I'd hope for battery life but I came from a Droid MAXX before it so I suppose there's nothing out there that comes close to that level of native battery life except the LG G2 and I haven't touched one of those.
As far as development goes, I would tend to lean towards it's basically dead for the Droid Ultra/MAXX/Mini at this point even in spite of them being so closely related to the Moto X/Moto G in some respects (X8 chipset, etc). It's a shame I suppose but that's how it goes.
