Dean,
I'm not debating the time it takes to get an ASN allocated... I'm talking about everything else around it... and changing your setup when you shouldn't even have to... again, you're telling people how to run their networks.
I'm simply saying that leave the running of the networks to them... let them decide when, if they multi-home, if they choose to de-multi-home, etc.
We all know we can lie our way around this... but people shouldn't have to... and if that is the only reason, then it is still a valid one.
A rule that isn't enforced, or has any repercussions for going around, shouldn't even be there in the first place. If the only reason it remains is to annoy some small number of ethical people, it should be remediated.
