I tend to be suspicious of code that arrives on the mailing list
day-one with a series of company-internal reviewed-by tags. Sometimes
there is preliminary work that can be done internally, but I think we
should prefer to do review in the open as much as possible where it
does not waste community time. Alex and I did reach a general internal
consensus to send this out and get community feedback, but I assumed
to do the bulk of the review in parallel with everyone else. That said
I think it's fine to ask for some other acks before you take a look,
but let's do that in the open.
