    that isn't so easy. Anything which doesn't have a performance tradeoff
    is in -O2 already. So every single thing in -Os costs you performance on
    a micro level.

    The translation to macro level depends greatly on how things are used
    (you even have to factor in download times etc)... so that is a fair
    question to leave up to the user... which is what there is today.
