add stage4 constraint - ease-of-minification

i think there’s an industry-painpoint (at least from my experience), of resistance adopting es6+ features because legacy-toolchains cannot be easily retooled to minify them.

i’m not sure the best way to address this problem? i favor requiring 2 independent minifiers to be able to handle a stage3-proposal before advancement (indicating retooling is feasible), but that may be overly-restrictive to some folks.
