You've forgotten "make --as-needed not break correct code by making
the linker ignore explicit instructions from a program author to
link two things together". Until you do that, --as-needed is in the
same category as -ffast-math.
And we can't be held hostage by few packages (marginal cases), that's
why we have function called $(no-as-needed) in flag-o-matic.eclass to
disable the behavior for these packages.
Will Gentoo be doing the same for -Ofast and its flags then? After all,
most packages work with them, and you can't let the few packages that
require standard-compliant behaviour from a compiler hold Gentoo
hostage.
--as-needed is a flag that tries to solve a specific (and very annoying)
problem. It deserves a bit of special treatment. It's not a ricer flag :-)
