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.
Also, it would likely help that new ISP in Myanmar
learn their limited upstream's communities if there
were a standard.
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.
