That was not my understanding, but we shouldn't be arguing over small
differences in percentages. We had enough of that on both sides of the
Atlantic already in 2016.

My understanding is that people were happy with the mono-repo as long
as it had the right balance between what's in the mono-repo and what's
That break down hasn't reached a consensus yet.

and how are we all going to interact with it.
Downstream users said "they will all eventually pay the costs" with
whatever decision upstream takes. They didn't say it was going to be
cheap (most of them said it was not), nor did they say that they'll
abide to whatever a closed group decision had formed.
This is an upstream process and needs to happen upstream, which means
the mailing list. Not socials, not IRC. This needs record, and the
mailing list is the only channel that has that feature and reaches all
