Should we block this from being backported to any branches?

I think we should also remove test/message/esm_display_syntax_error.mjs, test/message/esm_display_syntax_error.out, and test/parallel/test-no-harmony-top-level-await.mjs.

I think we should also remove test/message/esm_display_syntax_error.mjs, test/message/esm_display_syntax_error.out, and test/parallel/test-no-harmony-top-level-await.mjs.

Yes, I think we can remove these tests.

@targos @aduh95 Done. What about --experimental-top-level-await?

@GeoffreyBooth removing the flag from core would be a semver-major change since it is currently a no-op and removing it would cause node to throw with a bad option error

@danielleadams Wouldn't backport-blocked-v16.x label be more suited for the this PR? I think we do want this to land on v16.x.

@aduh95 yeah, that makes sense. I mean that #37468 should go in before #40226, but both should land on 16.x
