They must know Type Moon Fans adore the Backalley Alliance, right? Like, I've never met someone who didn't like them. The fact that they're left to rot in obscurity while every fate character under the sun is given time in the spotlight time and time again still kinda makes me sad- but here's to hoping that Tsukihimake while at least acknowledge them in a gag route or something.
They did release the "Back-alley Alliance Nightmare" manga back when FGO recently came out, so it's not like completely forgotten, but yeah I do wish we get more of them soon Probably after 'On The Other Side Of Red Garden'
