No, it's definitely a unique phenomenon of The Blood Tour.
That isn't to say that they've never dug deep into their back catalog before, but it was a fairly rare event. They were the sort of band that stuck mostly to their new material, supported by songs from the preceding couple of albums, with older staples and the occasional obscure (or very old) song thrown in.
And there are a lot of bands like that. Especially in the case of AFI, I get it. They're obviously more excited about new material that they find current and not done to death. There's always going to be a gulf between what an artist's perspective is and what their audience's perspective is. We love a mix of all their material, but the band wants to stay fresh.
It's encouraging, however, that they've made this a trend on this tour. Credit to Jade for designing these setlists. Hunter and Adam have also spoken about how drawing from older, rarer material (either never- or seldom-played songs) is exciting in its own way. Davey seems less enthusiastic about it, but even he admitted that performing songs like Paper Airplanes for the first time has been an interesting experience, as he doesn't typically listen to their older material.
