There are a number tools that require this information, some are not in our control.

We are not aiming 100% compatibility with GNU as it is impossible (and doesn't make sense) to copy all the corner cases like this. So even if it works with the GNU linker, we sometimes want to stop and think whether it semantically makes sense or not.

What we're trying to achieve is to place a non allocatable section into a custom PHDR, which to us makes perfect sense and isn't a corner case. However, we do accept that enabling this could cause interesting corner cases if mixing alloc and non-alloc sections in a PHDR.

Cheers,
