Not really.
The patches I am posting are to be able to have PPS and NMEA data on
separate device files for the NMEA refclock.
Frank (from the ntp folks, see the bugzilla of ntp) wanted no /dev/pps0
because that devicename was for the ATOM driver.

So the devicename change is by request of Frank.
In Linux we use a simple link to make the pps device findable.
