No, you're missing the point. More core OS upgrades means less incremental
patches (which are easier to apply than a full update). That means that
more systems will fall out of date because of the time-consuming nature of
full operating system upgrades.

Huh? That's backwards. If we can't schedule the downtime for a full
operating system upgrade (which takes far longer than it should) then the
system won't get upgraded. Small incremental patches can be built on
central systems and rsynced outwards fairly easily in comparison.

Not to be rude, but I think your definition of analogy is wrong. There was
no analogy in my comments - no parallelism at all. I was focused on the
single topic, and not referring to anything else.
Back to the point, the comments aren't "bad". Your idea that binary
operating system upgrades from ISO are "easier" demonstrates that you're
talking about home computers, not production servers. I'm talking about
production environments, which I made very clear in my description.
...few have CDs
...many don't have local consoles, or local staff
...many don't have local disks at all (flash-based systems)
"Install new OS from ISO" is completely impractical in all of these
environments. "Install from source" is impossible in most.
