Yes I can confirm you can Power Off and Power ON with just the remote control with the OpenELEC Kodi I tested with my new OpenELEC Jarvis release.

The point you make about different Kodi Android versions for AMLogic devices comes down to bugs in the XBMC / Kodi code itself or left over workarounds from older lower powered AML Android devices. That code being no longer relevant for 2016 devices. Backwards compatibility must still be retained however even if it is a PITA.

MINIX with their custom XBMC Android releases, name them XBMC to bypass Kodi Trademark restrictions when the device is sold. They also sign the custom XBMC Android .apk differently so it does not interfere with Kodi or get Auto updated from the Google Play store. These custom XBMC versions contain a bunch of bug fixes, and MINIX specific tweaks you do not see in the vanilla Kodi Android releases. This is a very good thing for AMLogic MINIX users.

Which brings us to the WeTek Core. Christian Troy, the Wetek Android dev. Does compile a custom version of Android Kodi containing AML specific bug fixes and Core specific tweaks as well. This version cannot be shipped with the device, but can be Installed by end users.
I believe (could be mistaken) as soon as Kodi Autoupdates, this bug fixed version will get overwritten as it has the same .apk signature as the vanilla Google Play Kodi. I don't think it is just Firmware updates that affects it.

I've been trying to convince CT to sign the his custom version differently so this does not happen, possibly even name it something else would be beneficial too. A new Logo for visual differentiation would be needed.
