Hey folks! Sorry, I don't know why it didn't occur to me to send this through the server list first, it was purely an oversight. I've sent a ticket to FESCo:
https://pagure.io/fesco/issue/3082
proposing we bump the max size of the aarch64 Server netinst image (which is release-blocking) from 700M to 1G, as the image is oversize for F39 final and the limit really doesn't seem to make any sense any more. A detailed justification is in the ticket. If you have passionate opinions on this, please read the ticket and comment. Thanks :)
