Thanks for writing this up! Some rough thoughts about the LMIC category:
1. I think the LMIC is a pretty useful category insofar as it’s used as “non-high-income-countries”.
2. Otherwise, I worry that folks might conflate with LMICs as just “low income countries”, when most countries in the LMIC category are lower to upper middle income (or developing).
3. I have a light preference for separating LMICs into two categories: “least developed countries” and “middle income countries”.
