To my knowledge, enabling the gsm-stack after a at+cpof requires a restart (at+cfun=1)

but traces won’t continue after that restart without re-enabling them.  
and as only a limited amount of traces is kept in local memory, getting that 3am bug is getting kinda troublesome

of-course this would need to be a selectable feature, as not everyone might want to use this behavior

Agreed!

If the unit restarts for any reason, it would be useful to have an automatic facility to restart tracing…

Already logged as an important enhancement, to be integrated ASAP.

my knowledge got expanded 😛  
you can use at+cfun=1,0 to restart the gsm stack without resetting the module 😃
