At the moment. You’ve literally just said yourself that there is a long history of smuggling code into comments. A few years down the line I don’t want to suddenly have the feature added and then have to be on the look out when I’m debugging a codebase for secret code in comments.

There’s also a long history of smuggling code into JS comments (JSX pragmas, pure), and seemingly noop directives (“use strict”). They’re all hacky but there’s a very strong resistance in the community to mixing intent with JSDoc (good luck signaling anything to TS or eslint in a JSDoc block!). I think it’s safe to write this possibility off as “probably not inevitable”.
