But then this creates an additional bounce message and Charles makes a
valid point:

However, I remember setting delay_warning_time for the benefit of
local domain senders, so they would get notification of delayed
delivery. If this is added, bounces to non-local domain sender would
be a side effect of deferring over-quota messages.

At any rate, thanks. I now have a good picture of what all the options are.
