To the best of my ability I believe that this is no longer necessary. I don't fully recall why this was first added but I believe it had to do with symbols all being exported by default and this was required to undo that. Regardless nowadays the default output of rustc seems suitable so it seems best to keep wasm in line with other targets.

The removal looks reasonable to me. Do we want to add a test here to check that wasm symbol visibilities generated by the current default rustc output don't regress in the future? As in, we have a default hidden visibilities codegen test but that seems to be |

I'd be personally ok skipping a test here since afaik this was just a quirk of the wasm runtime at the time which is no longer necessary. Everything's a bit different on wasm in terms of objects and such so I'd fear that a wasm-specific test might just add boilerplate to update rather than prevent a regression |
