Problem is PSON might become mandatory in the future. Exposing process model details in our public API has historically not worked well for us: basically all such APIs are now deprecated and broken. It's safer in the long run to just force PSON to be on.

If someone has a real good reason to disable it (e.g. small app loading only content from one security origin, want to avoid overhead of prewarming a process that will never be used) then I see the temptation to keep the setting around. But apps can break real badly if PSON is forced and they don't expect it. So I'm not sure this is a good idea. More opinions welcome.
