Since v1.1.108, the following runtime concepts appear to not be used anywhere.
Instead, these are duplicated in prototype concepts ("types"), where they are actually referenced.

CircularParticleCreationSpecification
CircularProjectileCreationSpecification
AttackParameterFluid
GunShift4Way

How I found out: I'm updating https://github.com/GlassBricks/typed-factorio to docs json format v5, and it's complaining that these concepts are never used anywhere. A manual inspection confirms this.

The variant fields of the AttackParameters runtime type weren't getting parsed. All the types are used there. I fixed this for the next doc release, thank you for the report!
