Default queue vs. no default queue

NTDEV
1

I’m sorry if this another dumb question:

What are the implications of creating a default queue (e.g. for read/write/ioctl)
vs. creating a non-default queue for the same callbacks?
Sure I have understood that all IRP without callback will fail in the latter case…
but what are the implications?

Is there a rule of thumb when to create a default queue and when not to?

It is a matter of convenience, in the end it is all the same after you have finished configuring your device
