Nit: 
I understand why this was put after `reference-types`, because this is a subset of that, 
but the feature names here and elsewhere are sorted by the feature name's alphabetical order so I think `-call-indirect-overlong` could go right after `-bulk-memory-opt`. All other places too. Yeah it's probably my OCD 😅 But having them sorted helped me find missing tings easier...
