Ignoring CCs and other 'gifted' sources of INF...
To a casual player, there's as much effort to building up that much INF as there is to actually working towards (or just unlock by playing normally) the bonus. The latter ends up getting you INF Anyway over time, so I really don't see where this would be all that beneficial other than to give those who've already been playing forever, have lots of INF, and just want to unlock the thing for other alts (Altitis anyone?). Hence why I reiterate support for the Globally unlocked accolades instead.
