There may have been a general idea that flag4 would be used to enable clockstats from an individual driver instance.
That's how refclock_shm uses it. I'd be happy if you nuked that test, aka always write it. (If clockstats isn't enabled it won't go anywhere.)
Same for refclock_gpsd
There may be others. I didn't check the drivers I'm not familiar with.
It's probably not worth a lot of work in this area.

The HP driver doesn't know anything about PPS. I assume that is a typo.

I would say "kernel PLL" in there. "discipline select" doesn't tell me anything.
These are my opinions. I hate spam.
