On Windows there is a (they called it) nightlies channel for Kodi, which contains not development versions but bugfix updates to the current stable version. It specifically states that these are stable versions containing only bug fixes, and while it does not explicitly state that they should be preferred over the stable channel the inference is inescapable.
Wouldn't it be a good idea to have the same on LibreELEC? That is, a channel where the core system (LE) is at the same state as the currently stable LE branch, but the Kodi shell is updated to the state of the currently stable bugfix update.
