It seems that spigot explicitly clamp the radius to 0. https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/nms-patches/net/minecraft/world/level/Explosion.patch#36 https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/nms-patches/net/minecraft/world/level/Explosion.patch#57
