As far as I can tell, these triggers were sent by xgsch2pcb, not by pcb. 
In this setup pcb-rnd (and mainline pcb) does not send out dbus requests 
to gschem, it is merely remote-controllable via dbus. And it seems the 
only dbus based remote controller for pcb was xgsch2pcb. So it was 
xgsch2pcb that told gschem to save and told pcb to import. I am 
deprecating this. Genxproj can do all these without dbus.

What is working fine, has been working fine and will be working fine 
without dbus (NO deprecation of any sort):

- pcb-rnd's import schematics (this never tried to do any dbus with 
gschem, see below); both from gui and from batch mode action scripts

- gsch2pcb-rnd (standalone tool)

- genxproj (external project)

As far as I can tell, the only effect of dbus deprecation will be that you 
won't be able to use xgsch2pcb with pcb-rnd (unless it's rewritten to use 
stdio communication to pcb-rnd). It didn't work out-of-the-box with 
pcb-rnd anyway.

(Note: I did check mainline code 4.0.0, the import sch runs gnetlist or 
make, but doesn't do any dbus there either.)
