I'd certainly prefer not to have to delete my (single) video source.
I'd think however that at least in my case with a single OTA antenna
source, as long as channel ids didn't already exist, I'm not sure how
they wouldn't get the same channids...given that the ids clearly use,
for example 1041 for 4.1, 1311 for 13.1 etc.

In the case of re-scanning however, what can change is the callsign.
I don't know offhand if the "This channel" rule uses callsign or
channid, but I know for a fact that single record uses callsign, which
on the record table is actually "station".  When I rescanned a few
individual transports some time back I had a few single record rules
break due to the change in callsign, which I was actually able to fix
manually by updating the rules "station" on record to match the
"callsign" of the channel (based on channid).
