My question persists as of why READONLY is needed
https://sourceware.org/pipermail/binutils/2021-May/116579.html

SECTIONS
{
     .note.package : ALIGN(4) {
         BYTE(0x04) BYTE(0x00) BYTE(0x00) BYTE(0x00)
     }
} INSERT AFTER .note.gnu.build-id;

ld-new a.o -T a.lds --build-id -o a


.note.package doesn't have the SHF_WRITE flag. No need for READONLY.
