Hi Nikolai, IMO this is a bad idea. The bleeding edge version is expected to be somewhat unstable, and exposing it via ELPA will lead to foot-shooting incidents.
On the other hand, it would be nice to have more regular releases from master to maint. AFAIK the last one was a year and a half ago (Org 8.2). However, this has traditionally required a lot of effort from Bastien and others, so it’s not a simple case of “wishing will make it so”. -- Aaron Ecay
