@LiviaMedeiros this will allow a cleanup of the numerous --js-float16array flags added to the test suite recently.

[LiviaMedeiros]

Thanks for the heads up, I'll do the cleanup if this lands.

That’s semver-major given that it adds a global, it would be good to have it on 24.0.0 although we’re way past the cutoff

@nodejs/tsc I think we should land this in v24.

Fast-track has been requested by @aduh95. Please 👍 to approve.

[LiviaMedeiros]

Would splitting this into two PRs or landing as two separate commits make more sense, since it enables two independent/unrelated to each other features at once?
