`@_exported` => risk of AppStore rejection?

[Sajjon]

I saw that the file FiniteField.swift uses @_exported attribute, @_exported import UInt256.

"But considering that it’s a private Swift attribute (as denoted by that pesky underscore 😒 ), we’re probably best off not using it for the time being."

Sound like there is a risk that the @_exported attribute can lead to AppStore rejection?
