...I'm not sure I buy that argument TBH.
"If they made it part of the syntax, that would require other implementations to implement it." ... I mean, so what? Has golang stopped ading new features to the spec? If not (which I guess so), then how is this any different? Unless you have freezed the language, this reasoning doesn't make sense to me.
The upside of that particular syntax is that only the parser used by tools needs to understand directives. All other parser implementations can be blissfully unaware, negating the need for special no-ops. The downside is...?
