Well, I guess you already checked the mail headers and found out
yourself. The question behind the question probably is "Why didn't you
CC it?". The answer to that is that I didn't have much success by adding
it to $RANDOM_THREAD. It might be more efficient to answer starting a
new thread with explicit "[RFC] $THE_ISSUE". Since a conclusion there
won't make the next merge-window anyhow, I haven't done that now. That
put aside, it might be more efficient if someone with a bigger urge
might strive for a solution (yes, probably, but not necessarily you).
For me, it currently is just one task which needs to be scheduled
