Binkd does not use the nodelist. It uses its own configuration files. Apples an oranges.

Some may do it, others may do it in a different way.
Listing multiple flags with different hostnames/ip-addresses BTW is not the preferred way. The preferred way of listing a multi-homed system is to use one host name and attach exta A or AAAA records to it.

It happened.

True enough. It is beyond the powers of the FTSC however to control this. We are at the mercy of the nodelist clerks.

There will always be people whose (perceived) needs exceeds what the system can offer and who refuse to adapt to the system but instead demand that the system adapts to them. You can't please them all, trying to do that will result in a bloathed system that pleases no one.

I do. The systyem as it has evolved does not provide for that. It can not provide for that witout redefinig flag use. To demand that is unreasonable as it is not backward compatible. It will make existing practise fail.
