Not sure if its specifically the reason but historically anything wishing to access the serial port needed to be part of the dialout group. pppd would need to be part of dialout to open a serial port so I guess they were lazy and used that group rather then creating there own.
pppd is not part of the dialout group today.
"ll /dev/ttyS*" will show you that all serial ports are still part of the dialout group, so removing it will likely break things. (I added myself back to the dialout group last week to talk to a device over a USB Serial interface with minicom).
The access rights of /dev/ttyS* have nothing to do with access rights to /etc/ppp.
Ok, In a previous age ppp would have likely used a serial dialup modem and to do so would have been a member of dialout which is likely where this came from. I was just trying to point out the history of how things used to be. Myself I have only configured ppp once and that was on a debian machine but maybe surprisingly only 2-3 years back.
