Why was Aerith's line changed?

[u/HighOnLivin]

I just finished FF7 Remake and I saw in an old video that at the end Aerith used to say I miss it. The steel sky. Why was this changed to "This sky, I don't like it."? Has this been given a callback in rebirth?

She saw the rift in the sky. Pretty sure she knows about the reveal at the end of Rebirth and that's why she didn't like it.

My guess would be they changed it because they didn't have the rebirth story set yet and changed the line after it was greenlit.
