It’s a good thought - we quite frequently end up fixing “bugs” that are just folks forgetting to add the Darwin-flavour section. One of my Grand Ideas (i.e. things that might never happen because of time) would be to split out the Well Known Sections used by GCC into file/files with .defs for the different flavours. This would mean one place to add a new GCC named section - which would make it much less likely for folks to forget to add the Darwin ones (assuming there are no targets left without named sections).
