Assuming the market is shifting to battery-powered mobile devices
possibly intended to run for days or even weeks without charging, I
think we're going to start seeing some more efficient apps. I don't
doubt the old behemoths will still be around for a while, but musl is
developed with the assumption/intention that efficiency is going to be
one of the important design criteria for future software. If we were
happy with the level of bloat you're describing above, I think lots of
people in this community would just forget about musl and use glibc...
