> I think a simpler solution is to just add a `: to_load` here. (We already have that for the `.text` section as well, although I'm not sure why. It is implicit everywhere else too, so maybe we should just make it explicit everywhere to reduce ambiguity.)

That works indeed. It's a bit confusing to have (NOLOAD) and to_load for the same section?
