And even if it was, I think the onus would be on anyone who wants to
preserve those saving, to come up with an automated way of dropping the
unneeded bits from the final binary *without* cluttering the source

The -ffunction-sections --gc-sections approach works relatively well,
and could feasibly be extended to identify those functions which are
referenced, even indirectly, from non-init code. Our tools already do
half the fun work of that anyway, just for validation purposes.
