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.

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.
