My usual starting templates in Logic are 8 or 16 tracks, with interface input numbers matching the corresponding tracks, and two Aux channels; one for short reverb or slapback, the other with longer reverb.
Each track is routed to both auxiliary busses already (but not necessarily engaged).
I tend to look at the Mixer window of the interface, as opposed to the track waveform rendering window. If there is no reason to look at the waveform, I'm almost always in Mixer window mode, or maybe split view with a tiny bit of a waveform peaking through.
I don't have a problem improvising from that starting point as needed though. I don't have any philosophical problems with editing, adding more tracks/track stacks/groups/busses, etc. If anyone wanted to achieve "undo" or edits, they could have done them back in "old school" era anyway, and did... just more laboriously. If I'm mixing, I have no problem living in waveform edit view, going gung-ho drawing automation curves, etc.
I change routing from the described default (input 1->track 1, etc) constantly, I'm not weirdly dogmatic about it. But certain things do tend to live on certain tracks/inputs, at least for the basics.
More than anything, it just saves some brain cycles and a little time.
It does sort of feel more like I'm working with a machine than when I just freewheel on some software, adding tracks as it goes along.
