Hi Joe,

In coming to that conclusion, have you thought about and explicitly
rejected all of the approaches that have been mooted to mitigate
those concerns?

Is there a strong reason why the following non-exhaustive list
would all be doomed to failure:

 * encouraging projects to follow the successful Sahara model,
   where one core contributor also made a large contribution to
   a cross-project effort (in this case infra, but could be QA
   or docs or release management or stable-maint ... etc)

   [this could be seen as essentially offsetting the cost of
    that additional project drawing from the cross-project well]

 * assigning liaisons from each project to *each* of the cross-
   project efforts

   [this could be augmented/accelerated with one of the standard
    on-boarding approaches, such as a designated mentor for the
    liaison or even an immersive period of secondment]
 * applying back-pressure via the board representation to make
   it more likely that the appropriate number of net-new
   cross-project resources are forthcoming

   [c.f. Stef's "we're not amateurs or volunteers" mail earlier
    on this thread]

I really think we need to do better than dismissing out-of-hand
the idea of beefing up the cross-project efforts. If it won't
work for specific reasons, let's get those reasons out onto
the table and make a data-driven decision on this.

OK, well let's brain-storm on how some of those efforts could
potentially be made more scalable.

Should we for example start to look at release management as a
program onto itself, with a PTL *and* a group of cores to divide
and conquer the load?

(the hands-on rel mgmt for the juno-2 milestone, for example, was
 delegated - is there a good reason why such delegation wouldn't
 work as a matter of course?)

Should QA programs such as grenade be actively seeking new cores to
spread the workload?

(until recently, this had the effective minimum of 2 cores, despite
 now being a requirement for integrated projects)

Could the infra group potentially delegate some of the workload onto
the distro folks?

(given that it's strongly in their interest to have their distro
 represented in the CI gate.

None of the above ideas may make sense, but it doesn't feel like
every avenue has been explored here. I for one don't feel entirely
satisfied that every potential solution to cross-project strain was
fully thought-out in advance of the de-integration being presented
as the solution.

Just my $0.02 ...
