@json-betsec did you do the manual test yourself?

Could you do a final pass/check before I merge this?

What do you think the risk of the PR is?
We could ship this as part of 7.5?

[json-betsec]

Could you do a final pass/check before I merge this?

I did a final check and this PR is good to go

What do you think the risk of the PR is?

I think this PR is very low risk

Could we ship this as part of 7.5?

Absolutely!

NOTE: I do think this file could just be:

import type * as _NextImage from 'next/image';

export const defaultLoader = ({ src }: _NextImage.ImageLoaderProps) => {
  return src;
};

Which could be considered, but hey, to make this release, this PR can be good to merge too!
