Interesting. I just did the experiment. I made sure that gpsd was not
running:

root@jhegaala:~# ps aux | grep -i gps
root      767310  0.0  0.0   6240   644 pts/4    S+   22:03   0:00 grep
--colour=auto -i gps root@jhegaala:~#


I then plugged my GPS receiver in, and checked again:

root@jhegaala:~# ps aux | grep -i gps
gpsd      767329  0.0  0.0   9156  2468 ?        S<s  22:04   0:00 
/usr/sbin/gpsd -G
root      767332  0.0  0.0   6240   716 pts/4    S+   22:04   0:00 grep 
--colour=auto -i gps
root@jhegaala:~# 

This on Debian 11, gpsd 3.22-4.

I then unplugged the receiver, and shut gpsd down. I then launched a
gpsd client. gpsd and the client both ran, although the client didn't
showing anything useful. I then plugged the receiver back in. The
client started to show useful data.
