I don't think this really demonstrates UEFI bloat. A tcp/ip stack from boot services is handy and useful for 'legitimate' network booting, not really bloat IMHO; pxe and undi is similar in a bios environment but ddoesn't necessarily come from the motherboard firmware. Access to input devices, such as keyboard and mouse is reasonable too. Graphical output seems reasonable too.
And then everything else is stuff the author did or linked in. Where's the firmeware bloat?
