Open Stack

I would argue Linus, yes. As he's constantly stepping up when a subsistem tries and breaks something for a user or creates a user facing mess and says, no, subsystem, no. breaking userspace is unacceptable, or, we're not adding support for an api we have to support forever thats very poorly designed. Yes, he defers a lot to subsystem maintainers, as they have generally gotten the message of paying close attention to that kind of thing over time, and he hasn't had to speak up so much anymore. The rest really is best left up to the subsystems. But someone has to keep an eye on the big picture. The users of the whole thing. Users care about the linux kernel as a whole, and less so about any given subsystem.

Thanks,
Kevin

I'll concede this requirement if you can point out to me who this group
is for the Linux Kernel.  If you're tempted to say "Linus", it's most
certainly not: while he does care about some architectural decisions,
he emphatically avoids most of them, which leaves the subsystem
maintainers (some equivalence to openstack projects/PTLs) doing this on
a case by case basis.
