How is that any different than any other network with minimal connectivity (say a non-ISP such as a school, medium business, local government, etc.)?
Also, it would likely help that new ISP in Myanmar learn their limited upstream's communities if there were a standard.

Consider a new ISP starting operations in Myanmar, with little or no
global peering, having to wade through tons of information to design
their BGP community structure based on a "de facto" standard defined by
a group of ISP's half-way around the world.
What's the real value?
