@stebet thank you for your ongoing contributions. FYI we may or may not have a chance to get to this till mid-next week.

@stebet can you please rebase this on top of master?

[bollhals]

Is this something that we consider doing? I might be able to take a look on that if you want.

[michaelklishin]

@bollhals yes, we have agreed that the generation part arguably takes more time to maintain than it saves. The protocol doesn't change very often.

[stebet]

Currently working on a rebase of the full-async branch. It's a bit time consuming but I should get it done in the next days. Ramping productivity back up after summer vacations ;)

I assume #924 supersedes this.
