Looks like all checks went through now 👍

I still need to add a formatter for stderr when the rest of the messages goes to a file. We don't want fatal errors to be formatted in json for this case. Will do asap and merge for 1.6.2

[mmetc]

merge is postponed to 1.6.3 since I'd like to correctly bubble up errors from goroutines and 1.6.2 is too soon

We keeping 1.6.3 or moving to 1.6.4?

Next one, I'd rather remove the remaining os.Exit and log.Fatal before implementing this
