The motivation is to avoid layout differences between `-no-pie` and `-pie/-shared`. If someone uses a linker script fragment with `INSERT`, it would be difficult if there are two layouts.

My original objection to doing anything for the `-no-pie` issue (#78521) was because I did not want to pessimize `-pie` users.

I think having two layouts is still an opinion, and I am eager to hear more opinions.

We could also have an option to select between the two layouts and figure out which default it should use. I don't know whether it justifies an option.
