Right so I am hoping that Randy’s answer helped here. The only thing I will
add is that it really depends on what gear you buy so in some sense I am
kind of wobbly on whether we should pick one.

I’m not sure which of Randy’s messages you’re referring to, but I would
this related reply (to the RtgDir review): "we do not tell operators how to
run their networks. for example many will choose operator driven because it
allows them to quickly swap new gear for a failed device without backflow
into the rpki. "

I’m not asking you to pick one…or to declare one to be the default/best..

I’m hoping that you can provide some guidance on the pros/cons of using one
method or another in different scenarios.  Maybe you say that if the right
hw is present then one method might be better…or you might say (as above)
that one method is better for some operational cases….

In any case, just a non-blocking comment. :-)

Thanks!

Alvaro.
