Because the existing flexibility of dis-aggregated BGP community
design can be done without any need to be in concert with the rest
of the world, and your network won't blow up. There are far more
pressing things to consider when launching a new network.<br>

There used to be a very large global transit network that did not
support BGP communities for their customers or peers. I'm not sure
if that is still their position in 2020, but back then, it did not
stop them from growing quite well.<br>
