Ah, I found it, in the README at /usr/share/doc/kio-fuse/README:

"The DBus service is automatically used by KIO (5.66+) when opening a 
file on a KIO URL with a KIO-unaware application."

However, it does not seem to appear to be triggered in this way here.

I went onto a fish:// directory in Dolphin and told it to open a file with 
Tea and ScITE as editors, both times I got an empty file, no KIO fuse 
mount and… no error message in ~/.xsession-errors, however I just 
recently learned that for DBUS activates services on non systemd as PID 
1 systems error messages may go to /dev/null. I am using runit as PID 1.

Best,
