Neither Affinity nor Caw-Blade was banned out of existence in Modern, as shown by the fact they were still being played after the bannings (admittedly, Caw-Blade eventually fell off the map, but it wasn't because of bannings). Also, while Affinity was legitimately banned out of existence in Standard, Caw-Blade was not, and remained a prominent part of the format even after the bannings.
I totally played Affinity after the banning. Pretty funny reactions.

^This. Says a lot about their priorities when they're concerned with Standard's staleness instead of depth.
