So what's the advantage of it being read-only at all?

Since the flag is clearly *used*, make it read-write, and then all my
objections go away (except for a slight worry that the dropping of
/proc/<pid>/autogroup_nice or whatever it is could break some odd
system app, but I don't worry *too* much about that).

Disabling autogroup is clearly something people might want, since the
code tests for it. So removing the flag entirely seems wrong too. But
if it exists, it should be writable. No?
