While I feel it is fair to keep the status quo, the decision here deserves some
additional comments.
It is true that potability is generally important, but the current way here is
actually not friendly to potability.
GCC and the GNU toolchain are not ELF-specific. Nor are they responsible to the
authority of the specification. The "ELF assumptions" have no natural position
to be the default at the very first glance from the users' view.
So the "portability" certainly include the ease of porting the programs to
different targets with different image formats back and forth. Sticking on the
ELF-centric defaults already fails (by reducing the platform-specific
differences) if users want to really gain more portability, at least for
PE/COFF targets (which do not support such interposition at all).
Although it is somewhat reasonable to distinguish platforms supporting symbol
interposition as first-class ones (same to the current "primary platforms"),
but this still seems technically weak.
Perhaps a more appropriate phrase for the reason is "backward compatibility".
