Ahh, nevermind, I didn’t get the proper context of the original post.
Freehubs have become one of the most PITA “standards”. The 11 speed Shimano and below, plus SRAM NX 12 Eagle and below, keep life easy. Go GX Eagle and above, or 12 speed Shimano, then you get into the goofy games. Both of those use two different freehub types.
